Thanks, again folks.

After the epoxy and visquine, I sanded it with 80 grit, wiped with acetone, and sprayed on some primer suggested by the guy at Lowe's. White shellac. When it dried 20 min later, I put on the first coat of exterior latex. Had taken a hundred color cards home, went back and picked up the closest match. The paint was room temp, applied to ~60 degree hulls with a foam brush. It's dry to the touch now and I can still see the brush strokes close up. Anyway to avoid or get rid of this? I mean you can't see it unless you get within a foot of the hull. At that point you can notice the perfectly smooth original gelcoat compared to the brush strokes of the new painted area.

FYI: I'm getting the surfaces warmed into the 60's with a couple space heaters and tenting plastic. Otherwise it's just now hitting 50, the expected high for today.
