Need some help. I have difficulty with airbubbles on and around the rails after the lam gels. The deck and bottom are clean. What do you do to have a clean airbubble-free lam job? Second Question: What is the best way to cut the glass so that it is razor clean? Thanks guys, Magoo
It is not uncommon to have some small (very small) airs where lams overlap. Other places around the rail are often the result of not having pulled the cloth around the rail tight. First, I would recommed working the edge of the lam – particularly the first – with a curved surform blade to make sure no edges or lumps are sticking up – do not use sand paper - it will leave grit and dirty marks on the resin. Second, set your resin so it starts to kick in about 20 to 30 minutes - when the resin starts to jell, it gets sticky. While it is getting sticky, go around the edged of the wetted-out cloth a second time with your squeegy and pull the cloth tight, particularly around the tail and nose. Most problems with getting the cloth tight are where you have a lot of curve in the outline. Hence, rounded pins are a place to be especially carful. I find a hard squeegy works best for thighting the cloth. Once the resin has setup compleatly, any larger airs should be cut away with the surform or a razor blade and repaired before the next lam or hot coat. Shine
