Well,.... My local Napa carries PPG paints,.....
Their line of fleet paint is called Prism,.... it's a 2-pt. poly based paint,.....
If ya get the "Anti-graphitti"(sp) hardener rather than the other hardeners available for it,...
Then mixed, 'n brushed, rolled, or sprayed on,.....
Once hard, 'n dry,.... Even other paints won't stick to it,......
We painted a hull with this stuff in red, several yearts ago,...... no fadin' as of yet,.....
When the boot stripe was painted on with another oil/ enamel paint, 'n allowed to dry,....
The boat was launched,..... within a day, the boot stripe washed off,.....
Had to pull the boat, 'n used stripe tape to put the boot stripe back on, which is now an annual affair,......
Of course, the draw-back is it's Expensive,....
