The basic rule for a maximum strength epoxy/glass lamination is: apply one ounce of epoxy for each ounce of glass weight per square yard,(i.e. 6 oz. of epoxy for each sq. yd. of 6 oz. glass). This, normally, leaves the weave showing. Additional coats of epoxy, such as fill coats, do not increase the strength of the lamination.
You seem to be on the proper course to keep the weight down.

: G'day, Could anyone offer some advice with not filling the weave after
: wetting out. I would like to keep the finished weight down and am thinking
: about skipping fill coats on all inside glass (deck/hull). Would this
: compromise overall strength of the kayak. Glass was rolled on with very
: good wet out. Kayak to be used in rough water - no rocks.

: Thanks
