I have some places that i need to fill with bondo or something.
I bought a anti-rust primer.

Could I use sand paper on the rust, apply anti-rust primer, then the bondo, and then another layer of the antirust primer?? (So that the bondo will not be on the surface where the rust used to be...)

Is that a good idea?

TIA.

Anyone?

Shai, I would just prime those spots until you are ready to do it right! Not saying your way "Won't" work, Just saying buying rattle can primer, then using filler then the rattle can again will most likely cause you problems in the long run. I would scupp all of the rust off, prime it with what you have too prevent future problems, then save up the money you would have spent doing patch jobs like that and take it too a body shop or get the right equipment and supplies and do it right. If I were you, I would spot prime like you are doing, and get a close matching color too coat the primer with if you want it too look halfway OK. Then save up all that energy and cash and do it right! Good Luck either way...

Shai, it's good to see you visiting the body shop now! That means you're ready to get that 4-door cruiser going!

Shai;

If you don't weld in the rust holes then it isn't a good fix. That's just the way it is.

Now, if you're only able to fill them for now, take a wire wheel on a grinder and clean all of the rust out you can and then use the "long hair" type filler. From the different ones I've seen/tried to use filling holes this type seems to work the best. Bondo will pop out almost immediately and fibreglass seems to chip/flake off in big pieces. The dry climate you're in should help it last.

Shia, don't put any primer under filler unless it is epoxy. Any spray can primer is going to get you in big trouble as the other guys have said.

Peter, if you don't mind let me build on your post. http://www.chevelles.com/forum/smile.gif

If you need to clean up rust I have found nothing better than 3M "stripit" discs. If I am calling it the right name. They look like a hamburger patty. You put them on a mandrel then on a drill or die grinder. Or the "Roloc" by 3M. They were originally designed for removeing gaskets. I have found them to make a wire wheel look like a joke.

And on the filler, the long strand fiberglass reinforced "bondo" is very hard to work with unless you are filling BIG TIME. There is a short strand filler that is almost like regular plastic filler (bondo) but is waterproof like the long strand. Evercoat calls it "Kitty hair". YOu can get it at a NAPA AUTO PARTS store under the name "Fiber strand" part number 6371. It is the same and made by Evercoat but in a NAPA label.
