I was wondering on everyone preps their frames for painting? On my K5 mini trail I just sent it to get powder coated but on my K1 CT70 I’m torn about getting it sand blasted first. The guy that painted my mini did a great job but I don’t think he would get “deep down” in the frame of my 70 so I was gonna get it sand blasted and primed myself before I send it to get painted. Should I use another method besides sand blasting? Any and all info is greatly appreciated.
