: Just finished glassing the deck on my first build. I'm a bit
: disappointed because I was hoping for a 100% transparent wet
: out, but I didn't get it. I'm looking for reasons why so I wont
: run into this again. I'm not new to fiber-glassing, just
: transparent layups. I used 6oz open weave glass from Noah's, Mas
: slow resin, heated shop to 85 along with resin, cooling to 80
: during layup, mixed small batches on a flat plate tray, applied
: with 3" West Systems roller, kept rolling to a minimum to
: reduce foaming. The areas that seemed worst were at the lap
: joint where I stopped to mix a new batch of epoxy then came back
: and continued the wet out. It's obvious the resin isn't
: completely soaking into the glass but I'm not sure what more I
: can do. I'm not starving it and I'm working as fast as I can and
: not dilly-dallying. While I'm wetting it out I can kind of see
: the trouble spots. If I take some time to massage the resin in
: that helps but still some areas just wont take completely. I
: have not ever worked with Mas Epoxy, maybe that's it, but it
: seemed fairly thin. I have used West Systems before and found it
: to be quite thick. I have also used Proset on a glider project
: and liked it quite a bit. I might try that next time. Maybe the
: glass is the problem? Or maybe I should use a squeegee instead
: of a roller and work it more?

: Anybody have similar issues or answers?

: I am a bit of a perfectionist and you can't see anything from a
: distance, but I'm not satisfied.

: This pic shows the result I'm getting. This is not all over but in
: more places than I like. This pic is after 2 filler coats as
: well.

Pretty boat.

One thing I tend to recommend often is practice and experimentation. People seem to want to not "waste" materials for experimenting, but it takes practice to make a clear (or nearly clear) glass job. Unless you can build several boats (which is alot of fun) doing test panels will save many problems down the road and may even be somewhat less expensive in the long run.
