Don't get the plastic body filler(bondo) thicker than 1/4" and it will be fine. Don't get it wet until it is sealed or it will absorb moisture. Rotted metal needs cut and welded new metal in.

Por15 for any remaining rust is a good idea. Paint over it to add some protection as its not made to be a topcoat.


If you have an air compressor, you can get dirt cheap spray guns and spray it with single stage paint. You could do a pretty nice job for $200, quality and longetivity would be much better than a rolled rustoleum job. If you spray outside early in the morning, the bugs and dust are not a big deal.
