I am building the millcreek 13 kayak from clc boats. I have gotten to the point where all my panels are cut and wire tied together. Last night I started to fillet and tape the inside bow section. I am using system 3 epoxy with a medium hardner and it starts to set up to quick in the mixing cup which causes me to try and rush as to not waste it. Will purchase the slow hardner to solve this problem. Now, the second problem is that I am using 3" wide 9oz cloth tape for the seams and is a little more difficult to wet out than I thought. Can it be thinned out a little with some acetone or styrene to get it to wet out the cloth a little easier without sacrificing any strength ? Luckily it was only a small section of the bow inside and I can fix it but any advice on thinning and maybe a mix ratio of epoxy to thinner would be helpful.
