Actually I took my laminated stock and used some Birchwood Casey Gun Stock Wax and waxed the laminated stock three times now, inside and out. I used a small model builders paint brush and painted it on nice and thick. Then buffed it back off.

I have noted that any liquid beads right up on the stock so I am not really concerned about the wet weather. Although from all my readings and talking to Washington residents, here in Wisconsin we have no where near the rain fall as you do.
