I have a question for anyone who actually has experience doing body work. My '71 Chevy i just got has some shit on it that i would like to fix, just some dents and dings. I do not want to use Bondo becaus i have seen how it falls off or gives really shitty results if not done correctly, but if that is best then i will use it. My question is, after i pull the dents, is fiberglass mat and resin good to use to repair the dents? I also looked at the Bondo and it said not to use it in layers thicker than 1/16 inch, then after that layer dries, sand it and do another layer, repeating until it is the right thickness. Will this method keep it from falling out like it does a lot of times. I always see people with that shit where it is all cracked and pieces of the Bondo are missing, that is actually how one of my fenders is right now. I know that buying new fenders is the best way to get rid of the dents, and i plan to do that sooner or later. this is basically just gonna be for right now, but i still want it to look good.
