I am still in the middle of replacing all 7 original?thru hulls. Two of the original openings (one 3/4 and one 1 1/4) are so?wallowed out?that I will have to use a boat load of 5200 sealer to assure they will stay in place. I am considering using some of the West System epoxy and fairing compound to line the holes and there by assure a better, firmer seal with the 5200. I'm sure someone has dealt with a similar issue? Your opinions would be welcome. I have some thin glass mat that I?may be able to?line the holes with. Would that make more sense?
