Been there, done all of that... I onwed a sign company since 1987 and sold it a few years ago to buy the soup company I now own with my wife. The tanks are the most expensive part.. need large tanks, spray setup (compressor/gun), a large shower area (for rinsing after running thru the graphics), and the film and chemicals to activate it. Opuni, dude, if it doesnt exist in HI, I would look into it. It would be something very unique... there are a ton of places CONUS that are setup to do it. Oh, and you need to have some painting skills, since all of them are basecoated before the process starts. Meaning, if you want skulls that look silver, then you have to base the part in silver, then apply the graphic over it. The films are transparent...
I, on the other hand am wanting to invest in a laser engraver... making custom speaker grills for the bagger world... check my ones I made for myself!
I was thinkin the same exact thing. I have wanted to get into powdercoating..but maybe this is the way to go. Will have to do some research about it.
