I'm at the same point on my High Boy. A friend of mine that works for one of the large (quality) hot rod shops suggested that I have the inside of the frame powder coated and ask the coater to tape off the outer edges of the frame rails and paint them the body color. Since so much of the '32 frame is visable on a High Boy you will never get the same finish between powder coat and paint, even if the color match is good. Something tells me to pick a process and color that can be easily repaired since my car is a "driver".
