OK. I have sanded the epoxy smooth to get ready for varnish (wood duck).  There are several spots where the fiberglass is visible, but still smooth.  When I wipe the dust off with denatured alcohol and it is wet you cannot see the fiberglass. When it flashes off you see the weave again.  It seems like I read somewhere that this would be OK to varnish.  Not looking forward to another coat of epoxy and more sanding.  I suppose I'll try a small test section with varnish to see if the weave pattern disappears.  But, if anyone has gone through this before it would be helpful.

I had the same on my wood duckling. It varnished out ok for me.  ---

As long as you have not actually sanded into the cloth, and it feels smooth, it will disappear when you varnish. -Wes
