Can anyone tell from experience how well a PU finish holds when flying in wave conditions, i.e. low temperatures & strong turbulence?
I'm considering to repaint my glider, remove old gelcoat apply T35 as filler polyurethane on top. Can I go wave-flying again with peace of mind? To what extent is a PU finish vulnerable to cracking due to change in temperature? There's tons of information on the refinish topic, but I couldn't find the answer to this particular question.

Thanks!
