Default Gelcoat Sanding

Hi Ramy,

i recently read an article on you in gliding international. you are an inspiration, i can only imagines some of the beautiful scenery you must have seen!

another possible reason to sand is if you can catch crazing in it's very earliest stages you can sand away the damaged gelcoat and literally remove the crazing completely. crazing most typically begins in the existing sanding scratches on the surface of the gelcoat. that's the reason they are often chordwise, because as mike opitz indicated above, the manufacturers used to sand chordwise.

I often hear that sanding is only a temporary solution, and after couple of years the gel coat will lift again and now you have a thiner gel coat layer and wider cracks. If so, why sanding unless you try to sell your glider?
