I've finished glassing my Guillemot-L using the five ounce cloth and 350/127 from Raka and I am pleased with the results. I think it lived up to the recommendation Larry gave me. The cloth draped well on the outside and the problems I have on the inside are some small bubbles at the bow and stern most likely caused by my inexperience. The 350/127 has a long working life, so I was able to work slowly. The cloth is flat so the weave was 95% filled with one fill coat. I used 18 ounces of epoxy to wet out the cloth on the deck (no saturation coat), six ounces on the first fill and four on the second. The 350/127 cured in about ten hours and the finish is so glossy that it still looks wet. Regards, Scott.
