Thanks for all the advice. I dont want to drop the powder coater in the dirt here. I stripped the bike completely and asked my brother to powder coat it at his work place. His colleagues normally powder coat gym equipment. They done a real good job on the frame but it was completely my fault the racers and crown were left on.

As I said, im a noob and have learned tremendously from this thread - so thank you. I wont be making this mistake again
