I guess we all can sue Johnson & Johnson for respiratory problems, just like the women are for use of Tal*** Powder for female problems
Back in Jr. High school when I bought my 55 Chevy, I used Black Knight. A few years later I switched to Bondo. When I did the body off restoration in 1997. the Bondo repairs had rusted again. The Black Knight repairs were still as solid as when I did them in 1978. The Black Knight really held up well. Doubt that it's still made, though.
For decades, this stuff. I've tried the RAGE and RAGE GOLD, a few other "miracle" premium fillers. Nope. Pinholes? Fold it out a few more times. Won't feather? Get the hardener right. All fill shrinks if its thick, I don't care how much you love what you're using or what you paid. The only near ZERO shrink was All Metal, but screw that ****. The extra work isn't worth it either. It's a finishing aid. In that context $100/gal is almost silly.
Just went to buy a gallon of rage ultra and the price jumped from $60 to $140 in a week . Damn I’m not spending that!
^^^^^ Damn, I can't put a like on that but I smell what you're steppin in! I hope all of us here know that almost any f'gl*** resin will work to cream up your mud a little. It's the polyester liquid in all of em just don't get greedy. It also makes it cure a wee bit harder overnight. When you need that little snick to bring spots together or raise an area, stir a little metal glaze in before hardener. Makes it block together real easy to avoid re-skimming too big an area. Just throwin it out there.
I used Bondo brand on our '41 in 1995. It never showed any signs of shrinkage or coming loose. I always put a skim coat on and let it set for a few days to gas off while working on another spot. We hit a deer in the front and demolished the front. R. front fender had to be cut off with a recip. saw but the skim coat of bondo was still holding on. some cracks where the fender was wrinkled.
