Alrity, thank you guys. I find it useful to check the werinkling on my wing my puting the covering against strong sunlight and see the light relfectiong from faults in the wing. Does teh sunlight exagurate the wrinkling? Because there seems to be much mroe wrinkling against sunlight than when i just plain look at it or pass my finger gently over the wrinkles, as the air will in real flight?

Yishht.
