My boards are feeling a bit heavy. I think I'm using too much resin. How can I make them lighter and not affect the strength?
If you're looking to reduce weight you can pull more resin out of the lamination so the fiberglass weave has no shininess, reduce the length of your laps (less material on board), and cut back on the hotcoat amount but make sure you're really good at sanding so you don't burn through.
