Paint all the way for me, much more versatile and easier to touch up if necessary. Powder coating is more susceptible to deeper chips which can look very unsightly if you do happen to pick any up, depends how hard you ride and how much you fall off.
That’s the 2 main problems with powder coating in a nutshell. I find you never get the “correct” colour you wanted, it always seems a little off, and it’s always “thicker” . Glad you’ve decided to go for paint, hope it looks great when your all done.
