: Btw, did you seal the Dacron with epoxy first prior to putting on
: the Vectra?

: Had a thought, when I first tried this method I tried to wet out
: the glass and the Dacron at the same time, acts like a giant
: sponge, sucks up gross quantities of epoxy.

Yup, per your instructions, I always seal the Dacron with a light coating of epoxy then laminate on the Vectracloth. It is very similar to Dynel. It also reminds me of Kevlar. 4oz Vectra uses as much epoxy as 8 or 9 oz fiberglass. I never thought it would stop sucking in epoxy! I also made a separate 12"x12" panel out of some scrap fabric that I laminated like the skin to use as a weight comparison of other skins. It weighed in at 1.7oz/SF = 15.3 oz/SY. NOT including two coats of paint. Even with all the epoxy it's quite flexible. The cotton/poly on the deck used a lot less epoxy. (No test panel)

The 3oz glass on my daughter's boat shouldn't use nearly as much epoxy. I'm making a test panel for that as well as the Dacron/cotton-poly deck. I'll report back with a weight when I finally get to glassing her hull.
