I'd prefer not to use it but just incase I do need to what would be the recommended body filler. I've used a USC Fiberglass body filler that I was told was pretty good in the past but I sold the car shortly after I finished the body work on it so I wasn't able to see how it held up. Any suggestions would be great. Thanks.
If put over properly prepared surface you will not have any problems with the modern body fillers,I happen to like FGE Rage filler myself. Rust is not a properly perpared surface,but if you do use a filler over welds or rust holes use a duraglass type filler as they are water proof and will not swell and crack like body filler will.
