We have a Raven I with 900 hours TT. I got a new canopy cover made about 6 months ago using the old one as original pattern. A few weeks ago I noticed a few spots (small bubble type) showing up on the bottom of the doors. Now it is all over the front and side of the aircraft, looking like a type of white chicken pox... Pierced one bubble expecting to see water maybe but nothing. SO is this a result of high condensation under the canopy cover (Tropical Moonson weather) or simply a case of faulty factory painting? Has anybody else experienced it?
