: Yesterday I placed a seal-coat over my hull and tomorrow I plan to lay glass.
: I used a roller for the seal-coat and there are spots that have
: "bumps" on the surface (I'm sure it's from foam). Should I
: lightly sand the seal-coat or should I just lay glass on top of it?
: thanks Danny

Oh man, don't glass over defects. Any bumps in the layups will both empty the nearby weave or raise the weave too high in the layup, and require sanding back to fair, which will sand away the fabric at the raised imperfection. Low spots will fill with epoxy like little lakes and likely distort the fair line at that point. Make your boat as smooth as a baby's ass before you glass it. Any defects, especially ones that stand higher than a fair curve, will print through prodigiously. Seal over sanded wood, sand, re-seal, and re-sand, then re-seal if you want your work to really shine. Don't try to sand the coats of sealer clear off, just sand enough to slightly lower high zones.

Seal your boat with strained material, like with the cheap nylon strainers that painters use, and use spotlessly clean containers for the uncured material.

I hope I'm not stepping out of line, I'm a newbie. But I was real good once, although I never vacuum bagged anything. Someone saw my work and told me that Lucasfilms needed me, and Lucasfilms was only about 20 miles away then. I should have gone over to check it out. I probably would have made a lot more money. But I was afraid of daily exposure to toxic fumes and ultra-fine dust.
