"Filling the weave"

Posted by Rolf Nilsen on Nov 17, 2005

I was just wondering..

When glassing the outside of the hull, you are supposed to use a squeege on the first layer, and the apply other layers with a roller.

Instead of applying up to 4 layers of epoxy with a roller, how about thickening the epoxy with a fairing filler? Cheaper, faster, faster sanding afterwards etc.. What would the "cons" be to such an approach? I can't see that the four layers do much structurally wise, expect as an additional safeguard against water/humidity?
