[QUOTE="DaleH, post: 519632, member: 15636"] Yes, [B]it could, [U]and will[/U] (especially if used in saltwater!), [I]if not properly isolated[/I][/B], but the hull I added this to was fiberglass, not tin ... Simple isloation for anything SS to tin can be accomplished by layers of duct tape, heatshrink on bolt/fasteners bodies, or nylon washers, just for example. For bolts, the US Navy even developed a 'goop' made expressly for use when adding SS hardware or bolts to their aluminum hulled detroyers and frigates, called "Tef-Gel". Expen[COLOR=rgb(226, 80, 65)][B]$[/B][/COLOR]ive, but works! My 1st tin hull refurb done 30-years ago or more ... I just used layers of duct tape to isolate the SS panels and/or hardware from the tin hull. About 20-years later the guy I sold it too called me and asked for advice on how I particularly attached something. Long story shortened ... he brought the boat to my house, I took apart that feature ... and lo' and behold, the duct tape was still sound and there was ZERO evidence of any galvanic corrosion between the 2 dissimilar materials, even on the SS bolt bodies or the surround tin they pierced through! I agree 110%, good thinkin'! [/QUOTE]
