I am having troubles with the varnish drying on my first kayak. I put the varnish on 5 days ago and it is still tacky. The places where it has dried it look scaly. If I try to sand it, the sandpaper gums up immediatly.

I put the varnish on over System 3 Epoxy. I thoroughly sanded the kayak with 150 and 220 grit sandpaper after letting the epoxy cure for 3 - 5 weeks. (some parts of the boat have cured longer than others) I cleaned the sanding dust with cheesecloth moistened with Interlux Brushing Liquid 333, then dry wiped it with cheesecloth again. The varnish is Interlux Schooner 96, thinned 10% with Interlux Brushing Liquid 333. I probably should not have thinned it, but it is too late now. It is over 70 degrees and quite dry in my basement.

Pygmy recommends ZSPAR's Flagship Varnish, but I was unable to find it in the stores around here. The people at the local boat shop don't know much about putting varnish over fiberglass.

I'm stumped as to what to do. Should I try to remove it? How? Wait for it to cure, sand it down and revarnish it? Should I use a different varnish?
