By 2K I mean a two component paint. It’s the paint + hardener. It’s what I’d use when mixing my own paint for my spray gun. There’s some options in rattle cans where you have another container inside the can that you “break” and the can is a one shot use.When you say 2k, are you referring to the clear coat? I used 2 cans of that stuff on my bobber paint job... I hope it holds up well, but after 2 weeks of sitting, I accidentally dinged a screwdriver off each fender while installing them, and it chipped down to the primer. Ugh.
