It seem that Polyurethane paints and lacquers are becoming more frequent choice for composite surfaces instead of gelcoats.
Am I right about that and what do you think is the reason? Surface quality? Weather (UV) resistance? Weight? Processing? Cost? Other?
As far as I know there was a lot of Polyester gelcoats use, especially in gliders, but why there is absence of epoxy gelcoat applications?
I know that gelcoats are heavy (typical about 500g/m2), but they can be still applied as a thinner coatings...
