I took my Chesapeake 17 out for "sea trials" this weekend prior to painting and varnishing it. When I had it out in the bright sun light I noticed a small area of the deck that seems to have a grid like pattern of tiny white "highlights" to it. I assume this must be air trapped in the epoxy from when I applied the fiberglass. In the workshop it looked like the fabric was completely wetted but appearently it was not? I am not sure that anyone but me will notice this but I am wondering how can I fix this? Do I have to sand through the fabric and re-epoxy the bare wood? Thanks.

RE: Deck Blemish Question
These blemishes ended up bothering me enough to try to fix them. I sanded down till the weave in the 'glass showed and the highlights dissapeared. After a coat of epoxy, they are no longer visible even though I did not sand down to bare wood. Go figure?

RE: Deck Blemish Question
That is good to know Scott. The same thing happened to me. However, the phenomenon did'nt manifest itself until the boat was out in the sun for a while. In addition, my boat was completely vanished already. I am absolutely certain the glass was wet out, however, it appears there is a tiny fraction of uncertainty in fiberglassing. No matter how well you think you did, you just can't be 100% certain this anomaly will not occur. Mine, like yours, appears to be trapped air in the wood trying to escape, as I can feel the bubbles trying to push through the epoxt, glass, and varnish. It does bother me, but it is only in a few spots, and no one notices it but me. Having said that though, sooner or later I will fix it, but it may be a while. Right now it's time to put some scratches on the bottom :)

Scott--live with it!!
Happened to me on one of my clc's. My problem was that when I was building this spring after I let the boat kick in the shop for a few hours after putting on the deck. I rolled it out into the sunshine. I do not have hatches and the air-bleed hole I drilled in the aft bulkhead got plugged with epoxy while I was installing the deck.
After about ten minutes in the sun the aft deck was balooning up- YIKES- I knew immediately what was going on- grabbed the cordless with a #11 bit and drilled thru the bulkhead to release the built up pressure.
Yup you can see the weave pattern, so it goes. I paddle my boat it's not a coffee table. The bottom looks worse than the top now since I've been using it all summer.
