I will be appling 1-shot to at new gelcoated surface, should I scuff the gelcoat slightly with a scotch bright pad or use something less abrasive like a dry cloth?
After using something on the order of Rapid-Prep, I have found just washing with water and Sof-Scrub, or Comet cleanser works well. Just be sure to rinse thoroughly to get the last of the powder off. Heavy on the water, light on the cleanser.

Aw well, I painted some numbers through a stencil yesterday afternoon about 6:00 and left them over night since I had plenty personal stuff to take care of. It was foggy this morning so you can figure what the night was like. I got a little antsy and pulled the stencil on one set early this morning and the 1-shot came off in a sheet. I cleaned it up and left the other side alone. By noon we were having good sun with 87 deg temperatures. The other side had some more drying time and the sun. The stencil came off easier leaving 2 small spots to touch up. I may have to leave some of the following work masked over night again. Is there any way of avoiding the early morning delay? I can not bring the piece inside.
Have not had good luck leaving stencil masks on too long. I think what may be happening is that the paint film bridging across from your surface to the stencil, or mask, is stronger than the bond between the paint and the surface. Try taking the mask off ASAP. Let your paint tack up to the point that it doesn't toss a spray back on the gel coat because of static electricity.

I think you are right, Bill. I was foolhardy to try to get the numbers on last night. I used a large flat and overlapped on the mask too much, so the bridge was over the entire outer edge of the letter. I'll mask again for the rest of the work, but will try to remove after 20 minutes or so. I will also be working with smaller brushes and working to keep excess paint off the mask itself.
FWIW,the little kid reminded me that lettering late in the day in a high humidity area is risky. Dew settling on one-shot before it's dry will kill the gloss, and leave you with an unintended matte finish. His contribution to the subject.

I had much better luck yesterday afternoon. Got a earlier start and pulled the masking off after tackup. I didn't go to the last minute and I was using unthinned 1-Shot, so hopefully the paint had a chance to dry enough, and the dew didn't settle on the paint to early morning. Thank the kid for the tip on late afternoon painting. It will be a reality until I can develope some speed.
