: i tried to glass the combing today and it didnt. nothing but air bubbles.
: i ended up pulling off the glass before it got too thick.
: wasted a bunch but there was no way i was leaving it on.

I find it easier to COMPRESS the cloth to make it conform instead of trying to stretch it, so generally I start laying the cloth around the widest part. In this case, the outside edge of the coaming rim. Ditto on Ken's suggestion on bias-cut cloth.

Curves with a very small radius are more likely to have bubbles, so it's good to make wood coaming rims a little thicker than a pencil (about 3/8" before sanding) and make little fillets on the tight interior angles. If the coaming rim is thinner, you might add a thin layer of wood over the top, which might look really cool, too.

Often it is easier to lay strips of dry cloth in the correct position if the coaming rim is first painted with epoxy. The cloth tends to stay in position when it has contact with the epoxy.

Some stubborn bubbles can be pressed into position when the epoxy gets a little more tacky.

If all else fails, I'd glass with smaller pieces of cloth.

It's tough an hectic for me too.
