I'm finishing my Yak with Epiphanes varnish, thinned with Interlux 333 thinner. The Epiphanes instructions say 3 hours to touch-dry, 24 to recoat. The weather here is cool & rainy, and after 24 hours, the varnish doesn't seem perfectly cured, a little "tender". Will warming the work up with floodlights help? What happens if the previous coat isn't 100% cured before the next?
