Saturday was a glassing day. Almost got all of it done but ran out of resin. Have a friend who works at one of the big boat builders in Wancheese. He shared with me how they lay their glass so I gave it a try. They mix Carbocil with their epoxy and then trowel it on. The glass goes on next. They then use a plastic trowel and scrape any excess paste out from beneath the glass. this is followed by brushing on epoxy followed by another troweling to remove excess. I had some release film that I then applied on top of that on part of it to see how it worked. I used extra slow harder to give myself plenty of time. End result. Its a really nice way to do it. Don't have to contend with a bunch of bubbles under the glass or excess epoxy dripping everywhere. The part that I covered with the release film came out really nice. Smooth and ready for spray fair. The other will require some sanding.

Interesting, sounds worth a try! What kind of release film were you using, peel ply?

I like to use a thixo hot coat as well. Especially for any deviations in the surface.

It works super well at holding glass on vertical or upside down surfaces as well; especially if the coating begins to cure and get tacky. Although wetout is generally done away on a flat. These types of jobs are tuff.
