Hello. I am buikding my first kayak (Frey by Bjorn Thomassen) and I am ready for glassing and epoxy on the hull. I have been planning to do a seal layer first, but due to temperature issues and the fact that glassing on sticky epoxy is harder (cloth not moving freely) I plan to let the seal layer harden and then sand it.
Is the difference in strength between chemical and mechanic bond large?
I will be painting the kayak
