Steve, Scott Grometer is an M15 owner out in the Northwest. He's off the air at the moment - I haven't seen a posting from him in the past month (vacation?) but just drop him a line, and he'll answer in due course. As for a sealant, you want something that seals, but is removeable in the future. not something like 3Ms 5200. Once that's in place you can't remove it without blasting! WEST marine catalog, 1999 edition page 173, gives you a listing of sealants and their recommended uses by product names. If you haven't got a WEST catalog, call them at 1-800-262-8464, and they will send you one. The WEST catalog of boat items becomes the common denominator amongst the M web site people. They just quote item and page number so you can find it. Connie ________________________________________________________________ GET INTERNET ACCESS FROM JUNO!
