Frank, Skip, Andrei and Tod, Thanks for the useful advice and help - that's exactly what I was looking for. The tip on appearance was something I hadn't thought about, and the caution about expansion was also important since the boards are a tight fit now in the mounting slots. I'm even concerned that the extra varnish coats may be too much. Sounds as if epoxy resin is the best bet, and I'll go ahead with increased confidence (hopefully not misplaced) with the job. I'll let you know what I did wrong after I do it. By the way, I stripped the boards using heat gun and scraper (also a first for me), and can't recommend it too highly. Easy work, no mess, and beautiful bare wood ready for finish sanding, sealing, and varnish. Next will be the toerails. Rick M-17 Lynne L ************** A Good Credit Score is 700 or Above.
