And don't varnish when it's cold or damp, not even retouch. The best time to varnish is in the middle of a hot, dry day, at least six months after the last brush stroke is dry to the touch. Cold and/or damp poses the risk of water getting into the varnish, and that can cause several problems.

I found a solution to this problem, one that was suggested to me by Dean Paules at the conference in D.C.
Since I live in Seattle (where weeks could go by waiting for a dry day during our rainy winters) I bought myself a space heater. I close up the studio windows and doors, heat up the room til it's pretty darn toasty, turn the heater off and apply the varnish.
Then I leave the room, closing the door behind me to keep the heat in, and wait a day or so until the varnish is completely dry. After that I go in, check that the varnish is dry, and open the windows and turn on the fan to vent all the varnish fumes.
I did this a couple of weeks ago and had no problems with clouding of the retouch varnish I applied.
