I consider Minwax as WBPU, not what you posted which can be considered auto enamel, which what that link shows as Marine enamel. Its like Eastwood European Clear 2:1, completely different animal than what I was thinking of. It is something I am planning to use on my B-25, but a spray booth is a must as the overspray can make a mess as it has a long dry time and can make everything sticky it lands on. It is 100% fuel proof though, and makes a nice hard high gloss finish that can be color match and polished. Considering that the B-25 Tootsie I am modeling after is a high gloss blue, I want to get as much shine as I can.
Downside is on fabric it can crack, where dope remains flexible to not crack.
