Holes in hull ?!?!

[Billybob]

The marine tex idea would probably work, and so would the 5200 idea, but here's what I would do.Take all your holes (take the ducer out), clean in and around them with acetone,patch from the inside with glass cloth and resin,patch it again from the inside with a little bigger glass and resin, now fill you holes from the outside (I used an Interlux bottom fairing putty), let dry, sand, and paint.O.K.,maybe it's a little more trouble, maybe I'm just anal - but even little match-sized leak can be a problem.
