I have a 02 Mobius lsv and just got new swim platform brackets and was trying to put the new ones on and cant get the top three bolts to tighten and noticed that they had some sort of caulk or epoxy that held the bracket to the hull as well as used to tighten the bolts as well. Was wondering what type of epoxy or caulk they used or what I could get that is just as good or better????

Thanks
