Held up extremely well on my wings done 20 years ago. The glider was out in the sun from April to Oct in Northern California and in a trailer outside all winter. No blister etc.
The page above details the refinish of the fuselage, it was also done 20 years ago with PolyFiber waterborne polyurethane that did not hold up at all.
The acrylic urethane used on the wings and the refinish of the fuselage was PPG JAU Direct Gloss Acrylic Urethane Shopline, 1/2 the price as the expensive stuff.
