I have a couple powdercoating questions.

I got a quote to spray my 73 World Voyageur for $120. I'm trying to match the blue (it's Schwinn Opaque Blue or something close to that), but have to source the powder myself. How difficult is it to match powder and who (if anyone) can do it affordably (like $100 or less)? The shop's quote was $450 to match, mask, and spray so I stand to save a considerable amount by doing it myself.

The chrome seat/chainstays, headtube lugs, and forkblades are getting masked. Is there some sort of hi-temp tape I should use to keep it the masking safe in the oven?
