Question about the rub rail. My boat is 94 and I have the aluminum channel with rubber insert type of rail. It is dinged and scratched in a few places but nothing worse considering year. My question is on a few areas on the bottom of the rail where the silicone is there are gaps not big but probably 1/4 of a inch. My main concern is of course hull seperation, it is a fiberglass boat, or should I just re-silicone. Anyone who has added new screws can I just pry out the rubber and push back in at the spots with gaps or do you have to pull out the whole channel. Thanks
