Sanding into the glass seems to be part of the process. The trick is to stop sanding as soon as the weave shows. Dry sanding the epoxy is better than wet sanding because the cloth is too hard to see when wet. If the glass is sanded through, then a glass patch is needed. Been there, done that. No biggie, just another set back.

If varnish is applied straight over the glass that was kissed by sanding, the glass print pretty much goes away. However, the consensus on this BB is to apply a coat of epoxy over the exposed glass and sand lightly before varnishing to assure moisture is kept away from the cloth to avoid long term problems. Be sure to give the epoxy two weeks to cure before varnishing or it interferes with the curing of the varnish.

: i'm feeling a little stressed after reading the green valley boat works FAQ!

: In my attempts to get the hull nice and fair, I have probably sanded into the
: weave of the cloth. Do I need to add a coat of epoxy (or two) cover the

: Also, has anyone tried varnishing a boat that is suspended from the ceiling
: so that an entire coat can be applied at once? any thoughts...
