What you did is probably overkill, but I am not convinced it will be a problem. Coarse grit is sufficient, but a finer sanding job will look nicer. There is some risk that the epoxy won't soak in well, but resin doesn't penetrate all that far anyway. I would apply a seal coat before the glass and then go ahead and glass it.

: The hull of my Cape Ann Double is ready to glass. I will be trying Raka's 5oz
: and will be applying a seal coat per Larry's instructions.

: My wood working experience so far has been in furniture, rifle stocks and the
: like. Consequently, I have prepped the surface of the hull to baby smooth
: down to using 0000 steel wool. While I wait for the glass to arrive, I
: have been going back through all the books and information I have on kayak
: building. The information I see talks about sanding with 120 grit.

: Have I gone too far for good epoxy adhesion? I am using West System epoxy.

: My gut is trying to tell me that the wood (WRC & Doug Fir) is porous and
: will absorb the epoxy for a good bond. The problem is that I am a type A
: and a worry wart.

: Any helpful experience or thoughts out there?
