Hi,

This is a little off topic, but I had a similar problem on one small spot on the "bright" deck ...some of my fiberglass came rolled from the distributor down the street, and a piece of masking tape was used to hold the cut edge in the middle of the roll - apparently there was enough adhesive left on the fiberglass so that it never wet-out completly and you can see a 1/2" x 3/4" area of silvery fiberglass cloth through 3 layers of epoxy and 5 coats of varnish - not enough adhesive residue to resist the epoxy wet-out, but still a discontinuity (if you know where to look). So watch out for that sneaky masking tape adhesive residue!
