I use a professional product, one of several, that you apply to bare
metal that do not inhibit using self etching primer. Sorry, I son't have
the exact part Dupont part #. It is in the shop across town. You can
find this sort of product at most jobber part stores. It is basically
just a rust inhibitor that seals the surface and is not photo sensitive.
I don't know if it still would do the job if you left it for an extended
period of time like years. Regular primer does not provide a moisture
barrier and neither does bondo.
The only way that I have gotten extend to work is to hit the area with a
scraper and stiff wire brush till all of the outer layers of rust are
gone. Then I have used extend to prevent the rust from spreading until I
was able to clean it up right, (blasting, cutting...). The product does
not penetrate thru thick layers of rust.
