Dan,
Go to my profile and hit the Send Message button under my photo to send a "private message". You have to be with the forum for a minute before you can send a PM so just in case I will I will try the same from here which should give you my e-mail.

Dan, I tried to respond on Friday but I must have pushed the wrong button or something. There is a Dreadnought ownerg in the Bay Area who has done what you are considering. He was very happy with the result. I think in his case it was Polyester Resin rather than cement but he should be able to help. Try to PM me. If that doesn't work I will leave my E-mail.
