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.
