My choice on beat up metal or welds is neither. I use a first fill of epoxy. JB weld or PC7. It sticks very well to steel... much better than bondo and is waterproof. I use bondo for final smoothing.


jb weld is not flexible it can crack or pop out if used on the body of a car that has a lot of flex. not the best choice for bodywork for sure.
