I've got a bit of rust under the front center of my hood...

Is there a way I can fix that? Can I sand it down to remove the rust and use touchup paint?
 
Sure you can fix it as you describe. You might need to use a wire brush on some of that, and maybe some of that rust reformer kind of stuff before the primer.
 
rust reformer?



I thought of a process like this:



sand it down (or wire brush), P21S Total Auto Wash (or similar), primer, touchup paint.



Where would I get the primer? Or do I really need the primer? What happens if I don't use primer?



Can I remove that latch that's in the way?
 
Interesting...



"Converts rust to black primer without sanding. Great for taking care of rusted areas. This is a very toxic product so use goggles, respirator and rubber gloves. Keep away from children!"



:eek:
 
Maxy--it can be very hard to paint over rust without it coming back. You definitely need to prime it or use one of those rust converters, I'm not sure all of them are as toxic as the one you referenced.
 
Yeah, use the converter. No way will it last with a regular primer- this sort of thing is tougher than people usually think.



The stuff you showed in your pic (hood latch area) should be doable as far as killing the rust with the converter, but I wouldn't expect much of a match with the paint. Mazda silver seems a little tricky to match just right anyhow (gee, ask how I know :o ).



I'd clean the area very well, mask it off, use a wire brush on a dremel, clean it again, apply the converter, and then think about what to do. The converter will hold up really well all by itself, at least it always has for me. At least the rust will be stopped from getting worse and this will be a bit of a project if that's all you do. Get up under the flange of the sheetmetal (top area of pic). You don't want to miss a little area and have it spread everywhere.
 
Hmm..I wonder if POR 15 offers a product that can be used first before repainting the area. Along with Eastwood Co, they're supposed to have premier products for this sort of purpose.
 
Unless they've come out with something new, the answer is "no". The two approaches (converter-primer vs. POR/Rust Encapsulator) are incompatible. It's an either/or thing. Both need to contact the surface being treated so whichever you applied first would mess with the one you applied subsequently.

18G is Highlight Silver Metallic Clearcoat, and that's from 2000. i didn't see 22G anywhere.

i'd call them up on monday and ask them to check your VIN.

I checked the doorjamb. It's 18G.
 
I'll probably end up getting the converter and everything. I don't have a Dremel tool though, so maybe I could use a cordless drill with a wire brush attachment? I think I have one of those.



And I don't have a respirator. I'll just do it outside on a windy day and hold my breath :D
