The manual doesn't seem to mention it, I just assumed that the stitch holes would be filled as I rollered on the epoxy. I've now done two coats on the outer hull and there's still light of day shining through many of the holes. I guess I'll make up some thickened epoxy and fill 'em up, do the screw holes from the rails while I'm at it.
I saw an earlier thread that advised filling the holes after the first coat of epoxy went on to make sanding more consistent.
Or I am over-thinking this? Maybe I should just be patient and they'll fill with epoxy and paint?
