Marine Tex on Donzi hull
 

Hi All
Im looking at a new used boat and on the hull toward the rear of the boat there is 2 small about the size of quater (not exatly round but about that general size) looks like gray marine tex no cracking or any thing around it just these two spots. Is that a common practice in a gelcoat repair onm the underside of a boat. Thanks for any advice.

Well I don't know if it's "normal" but I've marine-texed the bow edge of my hull where I got stuck on a oyster bed. It sands right on down to match the shape of the hull. Is it in anyplace to see the back side of the repair? I'd be worried about a hull puncture.

Yes i can see it its right in the blidge it has not been repair inside the is no sign of a puncture.

Not normal, but marine tex is a good product for that. Is it possible that the damage you see was caused by the bunk board bolts on that or another trailer?

FYI. I recall reading some where that polyester resin like gelcot will not work if applied over the top of the epoxy resin based Marine Tex should that become an issue.

poly sticks to epoxy and vice a versa, poly to cured poly has molecular bonding issues. read the data on the West system website very informative, lots of good info.

I chatted with them on line and you are correct and I stand corrected.
