HELP with bodywork
"is 2K primer surfacer the same as epoxy primer or is it high build primer?"
No. 2K is just an industry name for modern 2 component, urethane high build primers. Epoxy primers, in my opinion, should only be used as the first coat sprayed directly onto bare, clean, prepped metal, with body filler going on top of that, then 2K primer over everything. Most of epoxies don't sand very good, and most of the 2K's sand like butter.
"ALso guys, when would you use spot putty?"
If it isn't catalyzed then the answer from me would be never. Kombi putty or it's like is not catalyzed and dries much like lacquer based products, I wouldn't recommend them. I've used this product quite a bit:
Evercoat makes a similar product called "Easy Sand".
