Carl, I'm our club Puchacz (and our other SZD aircraft) have a factory PU finish. I haven't seen a Polish fibreglass sailplane with gelcoat (not to say they aren't out there).

The Jantar Std 2 s were. I've never heard of cracked finish on a Puch and they've been around long enough for that to happen if they were finished in Vorgelat. Unlikely they were Schwabellack finished gliders. You only need to remove ALL the gelcoat if it was cracked. Otherwise sand smooth with quite coarse paper, work down to a finer grit before repainting. If overspraying PU start with finer grit as you don't have much thickness to work with. Consult paint manufacturer about recommended undercoating. Ignore DMcD, he's trying to be funny.
