Hey Stan!
No mate I have no problems with acrylic. Those guitars look just as good a couple of years later. Used 2k Urathane on this cause I have spray room set up now for bikes with all the legal requirements. Filters and space suits etc... 2k is deadly to spray (very dangerous). But a hard finish and glossy out the gun. Also cures in 2 days. I used Nitro for my Nebulars but I use 2k for bike panels and have heaps of the stuff.
