I'll be using this kayak in swamps and small creeks, so I've been bulking it up a bit and I'm too concerned with adding little more weight. I haven't thought about dirt getting trapped, so I'll take a look at it later and decide whether or not to add little from the cockpit to the bow.
thanks for the input

: If you applied the fiberglass directly to the uncoated wood, then consider
: one weave fill coat. If you got any outgassing from the plywood, you might
