Yes, I read the report. Thing is, it appears that there is only one coating in the entire test that I would consider...POR-15. I'm going black in color with the bed, so the clear epoxies/urethanes, etc. just don't fit my end result.
I'm thinking that my test looks something like this....
POR-15
Alkyd Enamel paint from TSC
Polyurethane marine topside paint
Sherwin-Williams black stain
Black latex paint
Black oil base paint
The Mar-K test definitely gives a good glimpse of how to do it. Still can't believe that POR-15 stood up the way it did.
