While finishing the cockpit of my CS 17, a semi-dried "skin" of varnish formed in the can between coats. I decanted what I applied and sealed the can within a few minutes of openning it.
I hear the skin is normal, but I don't know how to prevent and/or deal with it as I turn toward the exterior finish. The main problem I had is that little chunks of the skin made their way to the boat as I applied subsequent coats. If I'm going to do six coats top and bottom, that's 11 times I have to deal with this.
I assume that removing the skin will not change the composition of the varnish - that is I assume the skin is not from a single component of the matieral.
