Ok I've just ran out of my last gallon of dupont 3919s prep sol and honestly I love this stuff. I've used it for years and never had a problem or complaint with it until now.... I can't find any for sale! I've tried the wax and grease remover but I don't care for it as much. I just bought some 3m prep sol 70 but damn 70 bucks a gallon?? So what are you guys using???
Dupont is now Axalta...maybe they sell it under a different name/number. Most solvent wax&grease removers are just mineral spirits with some additives. I use this one... https://www.amazon.com/Kleanstrip-P...ocphy=9021425&hvtargid=pla-569618139042&psc=1
a little googling....Axalta has First Klean 3900S, and Final Klean 3901S, seems like the names tell you what you need to know. Use First before you start, and Final before you shoot, eh? I would not be surprised to find they're both pretty expensive.
