Whats the best procedure to get rid of and repair surface rust on a car?

Answer 1

Surface rust is just on the surface of the metal, not pitted deep. Forget using these magic fixes, forget WD-40. What you need to do is get some sandpaper, sand the rust off, get it bright and shiny again, extend the radius of the sanding a bit beyond the known area of rust. Unless you are going to sand the entire body panel to bare metal you will want to feather the edges of the existing paint to get the smoothest repair possible. Once you have it cleaned throughly then go over the bare metal with a good etching primer/sealer, let that cure a couple days, and coat it with a good automotive topcoat paint. Surface rust is much too easy to remove to not do it the proper way, and really, this whole procedure will take maybe about an hour or two spread over a couple of days.

How To Fix Surface Rust

Answer 4

Forget chemicals. The only way of getting rid of surface rust is to physically remove it with sandpaper and elbow grease. Or (better still) an angle grinder and abrasive wheel / sanding disk.

Once gone, filler, zinc loaded primer, undercoat and several thin layers of top coat.

Unless your car is metallic, which is very difficult to get a match on using DIY materials - the original rust tends to be less unsightly than the repair in that case.

Answer 5

Mustang's answer is ace. Only thing I would add is to treat the bare metal surface with a phosphate product like "Jenolite" before using the primer. That will help to kill any tiny rust pits that have survived the sandpaper. For this type of job to last it's preparation, preparation, and more preparation that's important

Answer 6

Surface rust can be tricky. It might be deeper in the metal.

You have to clean, scrap, sand, grind and or cut until the metal is rust free. Then, depending on the damage, you will polish, fill, weld and paint to the original color.

loctite rust remedy. Sand rust down to base level, apply a coat of rust remedy and wait about 20 minutes until it turns black, then sand down a little to get a level surface and paint

Answer 8

I've used this Paint Over Rust (POR) product and it lasts a long time. You can paint over it with touch up paint.
