Can you apply it over rust?

I had some rusted areas, all I did was scuff up the rusted areas and applied the plastikote with a brush on the rusted areas and then went over those areas with a roller later on. If the areas are rusted to where the metal has gotten thinner than original, I would not reccommend going over the thin or brittle areas. make sure by tapping areas lightly with a light hammer or the wooden handle of a screwdriver. Hope my personal experience helps. It's hard to give advice without seeing the problem in person, but I think you should be alright if you follow this advise. Al

Interesting question. I used it to stop rust only on some parts I intended to paint. Since it chemically bonds to the metal if your intent is to eventually rechrome or repaint the part it may interfere with the process and require completely sanding it off. If parts are pitted this could be a real problem. Also when it dries it turns black which cosmetically would not be very attractive

The directions specifically state to use a 50 grit sanding disc to prep the surface to bare metal. You cover all bare metal with the adhesive so you get no surface rust.

I don't think that would work. This has rusted very quickly for me and the appearance is very disappointing.

Yes. Just make sure that you rinse it off and dry it when you're done. The water will oxidize the metal and cause it to rust if you leave it wet outside of the water.

Ospho will convert surface rust to black. You still need to sand and prime and paint

No, if you want to prevent the problem from worsening you must remove all the existing rust and then patch with bondo.

Hummm, I don't think it will survive the rust! Maybe if you spray a coat of rust proofing!

Here is their contact info. I would ask them directly. (I have rust spots bleeding through my paint from last year, but chalked that up to not getting it all off, and having spray shooting up underneath from puddles.) http://bondo.com/contact-us

No it doesn't work like that. You probably have to use that jelly rust product.

what ever you dont want to show peeling so on wire brush sand paper so on by no means do you have to get rld of all the rust this paint stops the rust and encapulates it remember they suggest to top coat this paint after proper drying you may use a color on top if you wish i suggest regular rust olium

I don't know where you live, but if you could get the bar sand or media blasted first that would take off any rust and loose chrome or anything else for that matter. If you can't do that you can just sand it by hand until you have a smooth and rust free surface and then use the primer. Another way is to buy a can of rust remover and shoot it on first, then sand and primer. The rust reformer will keep any rust from coming thru the new finish. You can purchase it on Amazon too. Hope this helps you.

Nothing will repair rust spots except stripping and repainting. This product will not work for your application.

Yes it can. It should help prevent some rust, however nothing else will work as good as heat resistant paint you can purchase at walmart for around 5.00 a can. Amazon should have heat resistant paint also. I find that to work well for me.

Hi Nathan, I agree with MOzarkian regarding the spray. I'd make sure to cover the entire piece, front and back well. I live in Florida, and we too decorate outside walls......clear sealant is my best friend!!! You might have less issue with rust as where you are it is a much drier climate.

it has the ability to cover rust. how good it will look will depend on the size of the area.

I'm sure you could. But you would need to put some kind of Rustoleum clear coat over it for rust control
