Just a general question about rust as I'm not familiar with bodywork or repair.I'm thinking about buying an old car 1970 that's pretty much a barn find.The paint is original and faded (interior is MINT) and there are small (very light) spots of rust starting Behind the rear wheels, and on the underside is the faded chrome bumpers.My idea is to restore the mechanicals but leave the very straight body paint and chrome alone.However I don't want it to get any worse! Is there anything that can be done to stop the progression?I won't be driving it in the winters, (or rain) and it will be garaged.Thanks
One step rust converter is available from many different manufacturers and dealers. It could be applied locally to the rust spots with a brush, gun, or swab. It will leave a black coating that can and should be painted over in order to inhibit further corrosion. Follow the instructions and precautions on the container. It will stain the paint and maybe the chrome, so mask carefully. I prefer the Eastwood brand.
The problem with that is I'm trying to preserve the original paint and "patina" of the car.I think I would prefer to to have it "fixed" and leave the small spots in primerRather than have shiny new paint in that area.....(I may just rechrome time the bumpers) but I think that may actually make the paint look worse?
I prefer having my car all one color too, so the answer is yes it will look worse with spots on it. But weathered paint preservation isn't my bag, I remove old finishes and fix the car. Rust has to be sanded off, converted, or cut out in order to stop it. A primer specifically for bare steel must be used and it must covered with a topcoat paint in order to protect the metal. Primer does not keep out the weather or wash water, and is destroyed by sunshine. Also, rechrome work is very expensive these days. I would make every effort to locate a replacement rather than rechrome.If I could see a pic of what you're talking about, I may have a better suggestion. "Minor rust" means a lot of different things to different people. Take a pencil or ice pick and poke the metal around the worst rust, you may have more than meets the eye. If you would like to discuss potential solutions that involve blending in new paint over old, just ask.
