Using Rust Doctor Products for Rust Removal on 1951 John Deere Tractor

Copy of tractor

Rust removal was made easy with Rust Doctor products. Here is Martin and his refurbished 1951 John Deere tractor.

Behind every restoration is a story. This story is about Rust Doctor customer Martin and his love affair with a 1951 John Deere Tractor “Johnny Popper”. Martin worked for a farmer as a young teen out in Montana helping to feed and care for 300 range cattle. In the early years on the farm, and until 1951 they used teams of horses to get the work done. A few years after WW II ended, the owner of the farm was finally able to buy a 1951 John Deere 2-cylinder tractor. At the time this was a very big deal and the local farmers from all over the region came to take a look at a machine that would make life easier. As Martin shared with the Rust Doctor, the first job of the ’51 was to work in -30 degree weather to take hay out to the cattle. Having a this John Deere tractor made this chore much easier, according to Martin.

Martin got a “call to action” during the Korean War. After serving four years in the Navy, Martin worked at several careers, including time with the railroad, Ford Motor Company, and happily settled in working for John Deere. Martin eventually headed west to California and is now retired. But he always wondered what happened to that ’51 tractor. Ten years ago Martin visited the old farm where he first encountered that wonderful machine. There it sat, in a field, old, tired, dirty and in desperate not of rust removal. Three years after that visit, the family that owned the farm asked Martin if he would like to have the broken down old rusty tractor. Martin jumped at the chance, brought it home and started the process of rust removal. Martin worked hard to restore it to its former glory using our Rust Doctor products, Rust Doctor and Grease Doctor. In a recent letter to the Rust Doctor team he stated, “The Rust Doctor products were the best way to go for this project with all of the rust removal that was needed.” Martin has recently converted the tractor to supports two riders. Now he and his lovely wife participate in many parades and events together. It’s great to see Martin reunited with his friend of 62 year – “Johnny Popper”. Yes, it was a story to be told. Thanks Martin for being such a loyal customer of Rust Doctor!

Rust Removal & Body Fillers

Hi. I have purchased the Rust Doctor to remove rust from my car hood. Not only is the hood rust covered, it needs body work. Is it okay to spread body plastic over it and/or will it hold up without any problems chemical or other wise?

Thank you,


That’s a great question Joe! You can apply body filler/putty on the Rust Doctor treated surface. Slightly scuff the surface with some 200 or 300 grit sand paper so you can get a “good bite” in the already treated Rust Doctor surface. You can apply virtually any product over a Rust Doctor treated surface, including fiberglass, bed liner and sound deadening coatings.

The Rust Doctor team had a real challenge when they decided to restore their own project – A 1969 Pontiac Bonneville Ambulance. Talk about rust removal! There was plenty of body work to be done as well, which included using body plastic. Then there was the painting, cleaning up chrome, and reclaiming the whole interior.

The ambulance had been used  at the Bonneville Salt Flat Time trials for several years in the early 70’s. The environmental conditions were rough and took its’ toll on the Bonneville. It was eventually was bought by a private party in Arizona and then the Rust Doctor team found it on Ebay and brought it home to Oregon. It was a “love of labor” as most car projects are. It took time to gather parts, prepare the ambulance for rust removal with Grease Doctor and then converting the rust permanently with Rust Doctor. It has now been restored to the beauty it once was. As many of you do, we named our car. She is now called “Bonne”. We take her to car shows, parades, and sometime take her to trade shows we attend. Maybe someday we will see Joe or some of our other customers in a show with their projects. Feel free to send us your success story and pictures. We would like to feature them on our blog. Just contact us at the Rust Doctor. Here are some pictures of the Rust Doctor 1969 Pontiac Bonneville Ambulance.

Remove Rust from a 2 Horse Trailer

I have a 2 horse trailer and it has surface rust almost everywhere.  How much Rust Doctor do you think I will need? I plan to remove rust from all over the trailer. This includes inside, outside, above, below, and the tongue. We are located in Colorado and want to know about applying Rust Doctor in an outdoor environment, as we do not have a indoor space to apply Rust Doctor for rust removal. Enclosed are pictures of our horse trailer.



Trailer Front Left Side

Trailer Back


Hi Keith,

The total square footage of surface area of your trailer is approximately 1,000 square feet.  That is two sides, the front, back and floor plus the tongue.  That calculation includes treating booth sides of the surfaces we discussed previously to remove rust.  Because you can paint Rust Doctor over rust and paint, you will permanently stop all rust on the surface and prime the converted rust and the paint. You can then apply a top coat of any color or any kind of paint. We would recommend a good quality industrial grade paint. Your local paint store can advise you on the best paint for strong wear.

The five gallon pail of Rust Doctor will cover a little over a 1,000 square feet, which is all of the surface needing treatment.  With each 5 gallon pail of Rust Doctor, we provide a free gallon of Grease Doctor cleaner/degreaser to clean the surfaces before you apply the Rust Doctor. You mix water with the Grease Doctor according to what area you are cleaning.  As you add water, you change Grease Doctor from a pure degreaser to a strong cleaner to a mild cleaner.  For lower surfaces on the trailer, use Grease Doctor fairly strong mixture to remove any road oil that is on the surfaces.  Higher up on the trailer you can use a weaker mixture.  I would use a fairly strong mixture on the floor and lower side walls.  Be sure and rinse the surface with plenty of water after using Grease Doctor to remove dirt, oil and any other contaminants that release from the surface by the Grease Doctor.  You will need to remove any loose rust or paint before you apply Rust Doctor.  You can use a pressure washer, wire wheel, Scotch Bright Pads or any system the works for you. 

Applying Rust Doctor in direct sunlight is not a problem unless the temperature is in the high 80’s and above because the metal would be so hot the Rust Doctor may dry too fast.  The temperature range for applying Rust Doctor is 40° to 100°.  Because Rust Doctor is water based, you don’t want to apply it when the temperature may drop into the low thirties.  You can apply it outside but I would put it under cover when you are done as you don’t want moisture collecting on the surface for 16 to 24 hours.  Rust Doctor will feel dry in about 30 minutes but it works on the rust for up to 20 hours until all the moisture in the paint has evaporated.  If moisture collects on the surface, it keeps the paint from drying properly. 


First I would like to thank you for taking the time to correspond over the past couple of days. I believe my approach will be applying Rust Doctor to remove rust when the weather breaks a bit.  There is still snow and it is not the best weather.  I think I will power spray the entire trailer after removing what I can (internal components of the trailer, the wood inside the trailer, windows, etc) and hopefully some of the loose rust.  Then I’ll allow the trailer to completely dry, pick three days where it looks like the weather will cooperate and follow your process.  Apply following your instructions and if I do it right, I will not have to worry about rust anymore.


We know you will be happy with how easy the rust removal will be with the Rust Doctor products. Your horse trailer appears to have “good bones” and will make it worth the time to remove rust from your horse trailer.  The Rust Doctor strives for quality “customer centered” service, so if  you have more questions about rust removal, please contact us.  We would enjoy seeing pictures of your completed rust free project when you are done. Good luck and happy riding!

Repair Rust on a Heating Oil Tank

I’m wondering if the combo of Grease Doctor and a couple of coats of the Rust Doctor would be appropriate for my heating oil tank which is getting quite rusty on the lower half (the tank is located inside my basement). The tank will be hard to access on the back (wall) side. Might I be able to apply the product with a mini-roller (and long handle)?



Hi Ian,

Rust Doctor and Grease Doctor will work well for you in stopping the rust and protecting the tank from future rust. You will need to clean the tank with Grease Doctor and rinse with water. Remove and loose rust or paint on the surface the best you can. A good way to do this is to apply Grease Doctor to the surface then brush the surface with a wire brush or a Scotch Brite Pad (sold in paint stores). Rinse the surface with water. Grease, dirt, oil, loose paint and rust will all be washed off with the rinse water. If you don’t have a drain in the basement for the rinse water, use a bucket and towels to rinse the tank. You can apply Rust Doctor to the rusty metal by any method that will work for you, including putting it in a garden sprayer to reach into difficult areas. If some Rust Doctor runs onto the floor, just wipe it up with a wet rag. Because Rust Doctor and Grease Doctor are water based, you will not be dealing with strong fumes or toxic chemicals. If you have more questions or need technical help about rust removal, please contact us.

We have more “tips & tricks” on our web site that might be useful for your project. You can also check out our video on how to use Rust Doctor on your rusty metal.

Rusty Metal Pipes & Industrial Use

Here is a good question from a company that supplies industrial pipe to companies and utilities.

A Pipe Yard 1

Good day, I have a few questions about your product, Rust Doctor. We are trying to come up with an idea for reclaiming pipe that has become too rusty for our customers requirements.

1. If we were to apply Rust Doctor to pipe that still has a partial coating would it only react  to the rusty metal  or would it peel up the coating that is still on pipe?

2. What, if any,  reaction would Rust Doctor have say to a rubber gasket, after dry of course…Your input would be helpful. Tony

Answer for those rusting pipe.

Rust Doctor only reacts with rust so it would not have an effect on any existing coating or  rubber gaskets. The basic process is to convert the rust to a non-rusting black iron oxide and leave a clear latex primer on the surface, including the existing coating. You will need to clean the surface with a water based cleaner such as our Grease Doctor cleaner/degreaser which is also safe to use on the pipe and existing coating and rubber gaskets. This should fix the rust on your pipe inventory to sell to your customers. The Rust Doctor has been used in many industrial applications for rust repair, including rusty large tanks, the marine industry,rusty beams in warehouses, rusting metal roofs etc. If you have more questions about the Rust Doctor or Grease Doctor, please contact us.

Rusty Trailer Help


I live in MN and have a snowmobile trailer that is in need of repair. I am wondering how and if your product would work on it. Thanks – Todd


Thanks for your question Todd. We get a lot of questions on how to remove rust from trailers. Rust Doctor will work just fine on removing eliminating rust on your trailer to haul your snowmobile. You will need to remove loose rust and paint and clean the surface with a water base cleaner/degreaser like our Grease Doctor to remove dirt, oil and other contaminants from the surface. Apply Rust Doctor to the paint and rust and the rust will turn to a non-rusting black iron oxide . The rust will be converted, leaving a clear ready-to-paint primer on the surface. You can top coat with any kind of paint. We hope you and your family and friends will enjoy many hours of great snowmobiling in Minnesota.

How Much Rust Doctor Do I Need?

We often get questions about how much Rust Doctor is needed to repair rust. Here is a typical question we get. If you have a rusty metal question about usage, don’t hesitate to call or email us. We have helped our Rust Doctor customers figure square footage on some pretty interesting projects, like rusted roofs, iron picket fences etc.

Question About Rusting

I have an all original 1964 pick up that is rusting.

I want to keep it for my sons, but I’m afraid that the rust will get the better of it before they do.  If I use the Rust Doctor  product to stop the rust today, will my boys have any issues in the future  with sanding, priming, and painting?

This would be in about 8 – 10 years.



Thanks for your question Bruce. Sounds like your boys will have a great truck to work on in the future. It’s wise that you are thinking about fixing the rust now.

Once Rust Doctor turns the rust to a black iron oxide, the rust is permanently gone. If you apply Rust Doctor to your truck and want to work on it any time in the future (years later if need be), all you will have to do is slightly scuff the surface with fine sandpaper before you begin priming and painting. The clear primer left on the surface after Rust Doctor is applied gets harder over time. Scuffing is not necessary within the first 30 days of application. One way to avoid having to sand the surface in the future is to apply a primer within 30 days of the original Rust Doctor application. This way you (or your sons) will not need to sand it before they choose their favorite color to paint that ’64 truck.

Typically, a quart of Rust Doctor will cover all the floor boards and trunk area of a car or the frame of a car or truck . If you need to do more than a frame, you will need at least two quarts. Each Rust Doctor quart will cover 50 square feet of rusty metal. The gallon will cover 200 hundred square feet which is your whole truck. Here one more resource from our Rust Doctor web page.

A Sears Mail Order Car

Imagine the love and elbow grease that was needed to remove rust from this1909 Sears Motor Buggy Model K. The Rust Doctor travels to several car and agricultural shows every year. While in Washington State, Wayne showed up at the Rust Doctor booth to tell us how much he liked using  the Rust Doctor products to remove rust from his project. A member of the Rust Doctor team went over to see Wayne’s amazing project. It was a beauty! This was an amazing mail-order motor buggy that originally sold in the Sears catalog for $395. We recently contacted Wayne for a “before” picture of his project. We couldn’t believe the magic he had done with his buggy! Thanks to Wayne for sharing his “before ” picture of his project. Look and see how Rust Doctor can work to remove rust without grinding or sandblasting.
