I wouldn’t, talk to the powdercoaters. If they’ve never done a bike before, turn around and go somewhere else. If they have they will use a high temperature green masking tape to mask the inside of the BB, head tube, seat tube, mech hanger, mud guard bottle threads..I thought so....... I think I can engineer a solution to the headset as far as the crown race but, thinking about it, if I'm going to replace the HS and BB is it worth leaving them in to protect the frame threads from the blasting media and powder coat?
If we’re talking tools... I managed to get a 2nd hand Park tool CRP1from a retiring bike mechanic.... it’s a dream to use..I get distracted for a short while because my new to me frame has finally arrived and all this happens.
I use one of these to remove the crown race, works ok as long as you are careful and it's not too expensive
