If I am understanding correctly, you would place the peel ply as the topmost layer with the fiberglass below and wet out with expoxy as normal.

The advantages would presumably be a smoother, more consistent surface and less amine blush. Are there others as well. I suppose the die-hard perfectionist (which I am not) could even use peel ply over the whole kayak?

In your example,with the North Star,after removing the peel ply you can apply the fiberglass to the deck/hull seam and wet out without preparing the surface before hand by sanding?

Hope this is not too redundant as I am only trying to clarify...
