Have used it on many various projects, but none that would really apply to the types of equipment related to this forum ! In my humble opinion, due to the price, complexity of formulation variables and projected durabilty, you would really be closer to ultimate satisfaction with a true C.A.R.C. product.
I realize that you have not specified an application or desired finish, so I may be talking out of turn ! This sight does cover aviation (Highly recommended and designed for), and various other arenas of interest, and I look forward to other opinions, but I will say that even with my experience with street rods, custom show trucks, (Chrome Shop Mafia) and fiberglass boats, after all my years of being a DuPont Imron fan, I actually started seeing better long term results from the Ditzler/PPG Deltron base/clear system.
And I cannot say enough about their DP40 (and other colors !) epoxy primer system for long term durability, but again, my next project will be a M35A2, and after all my research, it WILL be the Sherwin Williams water based C.A.R.C. system with a 383 green base !
But, as we all know, opinions are like ---holes, and if you ask 5 bodymen for an opinion, you will get 7 answers ! Research, Review and do it right, in YOUR opinion, the first time !
