the bottom corner of my driver door has 3 small rust spots. its not big enough to actual replace with sheetmetal though. would u think fiberglass and resin be the best way to go instead of bondo?

Are they small enough that they can be ground down and welded up?

slick66stang

yeah but i dont have a welder or know anyone who does.

Bummer, I think I would use some duraglass for a small patch. I'm trying to think how you could use glass mat and resin,from the inside out then putty over it?

this is what i did for my passenger side door since the bottom half of it was rust or wasnt there. i soaked the matte in resin and layered it so it was a new door skin i then let it dry a bit and placed dry matte on top of it and rolled more resin on that and sanded everything smooth and primed it. u cant tell it was rusted or made of fiberglass till u pick it up

That's pretty clever,you pretty muchbuilt a home made doorskin Heck,if it worked on thepassenger sidewhy not do it again.

yeah the only bad thing about my car is both frame rails are rusted on 2 sides. but thankfuly fiberglass fixed that probelm for now

If I were you I would cut the bad metal out. Cut 1" further than the rust and then weld in a small patch. Do it right the first time and never look back. You will be glad you did in the long run. When ever I have to weld small projects I go rent a welder for around $40.
