: By brother and I have the first of our Guillemot S&Gs fully glassed and are
: itching to give it an advance trial before varnishing, painting, and
: fitting out the final details. My questions are: How much direct sun
: exposure is OK prior to glassing? I'm planning on 2-3 hours in the glaring
: summer sun - any risk there?

2 or 3 hours in the sun is plenty to cause a noticable color change. Take a scrap of material and put in the sun, with half covered and after the 2 or 3 hours check the color variation. This may give you an idea what you will be facing. May not be as severe with the glass coating, but, will be close.

: How much cure time should I allow my final coat before getting it wet (I know
: this is a very relative question... ambeint temperature around 80 degrees
: and humid, Raka standard/fast hardener mix).

: After the trial run, we will be taping the seams and glassing my brother's
: boat. Is there any problem letting mine sit without paint/varnish for a
: couple months (in a basement)?
