          Comments about Marine Grade Silicone Sealant:

          This stuff is the bomb!! i had a issue where the keel gaurd was not sticking is two spots, the worst was along the mid point of the keel where the gaurd had a 1 foot section that was coming off the hull on one side, after preping the area and drying with denatured alc. using a wet/dry vac-cleaner to insure no residue, i filled the gap from the bottom and sqeesed the sealant to the top and wiped off the excess, used the straps to secure a brace against the repair an d after 48 hours it's perfict.
