I think they look great and hold up great. I wouldn't think they would store anymore heat then chrome does. I had hpc shoot a set of pipes in bonded chrome, looked awesome. Jet hot is a good company to get them done by also
Blue and pink, blue and yellow, blue and orange, blue and red, try putting a warm color to offset the blue plastics. -Coming from an artist. If worse comes to worse and you can't decide do everything in black, black always looks kickass with blue. Good luck
