I have seen silver vht last muchhhh longer than black, although I don't think anything is gonna stay shiny very long except ceramic (ceramic=professionally applied, not the vht spraycan that says "ceramic")...other than that?...here is what I have found...1. If you ride in the rain, it ruins the paint. It will be immediately dulled and completely fail, burning off soon thereafter. (soon=1000 miles?) 2. It is only gonna last so long anyway. My spray bombed pipes need re-done, on average, every other riding season. Granted, I put a lot of miles on my bikes. 3. Powder coaters often offer a "ceramic" powder coat. This is not much better than a spray can. The good stuff is chemically bonded to the surface via spraygun in a controlled environment to an extremely clean surface (can't vouch for it because it is too much of a hassle and too expensive for me)
