We heard from a customer who want to restore their Series Land Rovers. Land Rovers come in all sizes and styles and take a lot of wear and tear. Rust Doctor is perfect for rusty metal problems on Rovers and all things rusty metal.
I really like the idea of using Rust Doctor on some of the steel parts for our Series Land Rovers. However, I am hesitant to do so without a little more information. In my reading about magnetite and industrial applications of iron oxide, my understanding is that heat has to be applied to make it work and some type of coating applied thereafter to preserve it. I am wondering if you can tell me how Rust Doctor does this without the need for applying a lot of heat to the steel. If it makes chemical sense, then I am keen to try it!
Do you have any data on the length of time one can expect Rust Doctor to protect the steel in various environments, assuming 2 coats are used, all instructions followed and paint applied where appropriate?
Examples: Vehicle chassis
Steel door frames in vehicles
Steel stair railing outdoors
I would not intentionally apply it to aluminum but given that Land Rovers have some steel supporting parts and aluminum body panels, is there any adverse reaction if a little Rust Doctor gets on the aluminum?
Thank you very much,
Thank you for your interest in Rust Doctor. I imagine your Land Rover’s get a lot of action and they are now ready for a “update”.
Rust Doctor has been used in the marine, automotive, agriculture industries for almost 20 years. It uses a chemical process to convert Hematite (rust) to Magnetite. There is no heat involved in the conversion process. Magnetite is inert and therefore will not react to water and oxygen so it will not rust and protects the base metal from rusting as well. Depending on the thickness of the converted rust, the base metal will never rust unless the magnetite coating is very thin. In addition to converting the rust, Rust Doctor leaves a clear primer on the surface so you can top coat once the Rust Doctor has cured. A Rust Doctor treated surface has three layers of protection; a magnetite coating, a very good primer and the top coat. In most cases, the treated surface will never rust again. Generally only one coat of Rust Doctor is needed unless the rust is very thick. If two coats are used, the second coat would be applied while the first coat is still tacky. You can use Rust Doctor as a primer on Aluminum.
Here is the basic process for restoring rust and paint with Rust Doctor.
You can apply Rust Doctor over paint and rust. The Rust Doctor will find any rust on the surface and convert it to a non rusting black iron oxide called magnetite. In addition, a clear primer will be left on the surface of the paint and converted rust so you can top coat the surface with any kind or color of paint. You will need to wire brush the surface to remove any loose rust or paint before you apply the Rust Doctor. Be sure there is no loose paint on the surface as loose paint means there is rust behind it. Rust Doctor must come into direct contact with the rust to convert it. We have found the best way to prepare a surface for Rust Doctor treatment is to apply our Grease Doctor water-based cleaner/degreaser to the surface and work it in with the wire brush or a 3M Sanding Pad and then rinse the surface with water. You can use a pressure washer for this process as well. This removes dirt, grease, oil as well as the loose rust and paint. Remember you only need to brush the surface enough to remove loose rust and paint. If the surface has tight rust and paint, only a minimal amount of brushing will be necessary. Don’t be fooled by what looks like a clean surface. It always best to clean the surface before applying Rust Doctor.
Once the surface is clean, you can apply the Rust Doctor. Use a brush or spray gun to apply the Rust Doctor to the surface. If you use a conventional spray gun, use a 19-22 tip. Undercoating guns or Airless Spray guns work very well with this product. You can put Rust Doctor in a pump-up garden sprayer to reach hard to get at places. Rust Doctor will not hurt rubber, glass, plastic, wiring or paint. If you get Rust Doctor on a surface you don’t want it, wipe it off with a wet rag. You can clean your brush, spray gun and etc. with soap and water. There are no strong fumes when using Rust Doctor.
The primer Rust Doctor leaves on the surface when it dries will accept any kind or color of paint, primer, bed lining material, sound deadening material, body filler and fiberglass. You can weld on Rust Doctor treated surface because the magnetite is a metallic structure. When you weld on a Rust Doctor treated surface, you will burn (only light smoke) off the clear primer on the surface. Once you have finished welding and grinding the surface, paint the area with Rust Doctor so it will be primed and ready to paint. The primer on the surface can withstand about 300 degrees of temperature. If your welder is not burning off the primer quickly, you can just knock off the primer where you want to weld with a wire wheel on a drill motor.
Basically treating rusty metal involves a three step process:
1. Clean the surface to remove any surface contamination.
2. Remove any loose rust or paint.
3. Apply Rust Doctor
