I Have the VHT paint, in flat black on the head pipes of my Lemans IV, and on the RZ 350 expansion chambers. Its been at least 2 years, and holding up well. Spilled gas didnt seem to affect it.I have not tried any other colors, though. Its a thin paint so a few coats work best.
The local chain auto parts store,carries a selection, and I like the convenience of buying it local, and doing it myself.
Rick.
