: Pouring resin onto glass will float the glass on the pool of resin. If that
: resin is not quickly spread, excess resin will be
: trapped under the glass and add weight. This a common problem inside the
: hull.

I have been wondering about this idea for quite awhile as I see it stated often. By itself I don't think glass naturally wants to float on resin. At least it's not my experience. I got curious and put some short glass fibers in a cup of resin. They sank. Carbon fiber strands also sank. Resin and hardener mixed (from MAS specs) has a specific gravity a touch over 1.00 while glass fiber is much heavier with a specific gravity somewhere around 2.5 and carbon fiber is around 1.8. I'm guessing the primary culprit is squeegee technique. Vigorous squeegee pressure towards the sides will pull cloth off of the wood on the inside of a curve and thus suck resin through the cloth towards the bottom. This is not good. On the outside of a curve the opposite will happen and should result in a nice tight layer of glass. Other factors could be an issue. Things like trapped bubbles or wrinkles. So, am I missing anything?
