Mboaters: I've purchased a new main for SCRED, my M15. This sail has two reef points so I'm in the process of setting up the boom to for the necessary second line. For attaching the second eye strap, bullet block and clamcleat I'm looking for opinions - aluminum rivet the items in place (as done with the other hardware); or, stainless steel screw the items in place? If riveting in place, what 'grip length' for the rivet? If screwing in place, what length of screw? I've seen in other's posts to use 'never-seize' to avoid problems between stainless fittings and the aluminum. In the local hardware store i've found 'anti-seize' by PERMATEX. Are these the same products? Dave Scobie M15 #288 – SCRED visit Scred's www-site: http://www.freewebs.com/m15-named-scred
