My bow cleat is loose - can't screw back in nor loosen to put in bigger screws. Can't get to base on the inside as it is too forward. Wanted to slide in a bolt with those spring loaded "t"s that pop out once you insert, but can't get the current screws out. What to do? Squirt in fiberglass like substance? Bondo? Lots of glue is one solution but not the right one...
