hull coating.

[kmaysob]

hello all, i posted a while back about painting my boat and now have decided to paint it with gluvit first. gonna coat it pretty thick and then paint. i had another thought while i was at it. has anyone ever coated their hull with something like spray in bed liner or undercoating? im thinkin it would be good abrasion protection when i need to pull it onto the shore. any reasons not to?

Re: hull coating.

It would slow the boat down alot if you coated the hole bottom. But maybe if you just did the part that hits the most when you beach it, it would work ok.

I can't imagine why you would gluvit your entire hull. And I think you'd have to do an incredible amount of beaching to wear down an aluminum hull.

Most of the truck bed stuff is pretty heavy, but using the right one and only doing a smallish area would work, they also make Keel guards for aluminum hulls, which would be easy to apply. Unless you have a need to coat the entire bottom with Gluvit, I can't see where there would be any benefit. Aluminum drift boats sometimes use Gluvit on the hull, but not to protect it, its because it slides over rocks much easier than bare aluminum, which is very grabby.

Wouldn't coating the outside of a hull with bedliner make it grippy? It would be difficult to roll it back on a trailer! Get a keel guard.

Re: hull coating.

well the gluvit is to seal all of the rivets. not for abrasion resistance. i hadnt planned to use the bed liner on the whole thing. just on the "v" where there are alot of rivets. the idea is that gluvit will seal everything, and the bed liner will protect the gluvit on the "V". the portion that i want to coat will not be contacting the bunks on the trailer.

Re: hull coating.

Then just coat the rivets not the whole thing. Plus I think it would cost you a fortune to do the whole thing.

Re: hull coating.

Some people who have "drift" boats have used gluvit as a "barrier coat" on the entire hull bottom.

Everyone above has mentioned it and I will echo it.... a keel guard since that is where the majority of the wear will happen regardless of what a boat is made of (wood, fiberglass, aluminum) the keel takes the beating.

Have you flipped your hull over yet? That will be a good indicator of the wear areas. On my aluminum boats the keel up near the bow and the rivets along the bottom of the transom have shown the worst wear.

If you do decide to use a coat of gluvit on the entire hull bottom.....then you will have to prepare the gluvit by sanding again to take a primer then paint if you desire to paint the hull.

I have seen mixed results with bedliner being used on aluminum hulls. I have seen it separate in places (maybe due to aluminum oxidation??) and I know it must be applied thick and heavy. Absolutely not one of my choices for the bottom of the hull.

Re: hull coating.

well the only problem is the keel guards i have seen are over 100 dollars. i was already planning to seal the whole boat with gluvit and repaint it anyways. then i thought about the undercoating. i really only want to use it on the keel where theres a ton of rivets. my thinking is, ill be wasting my time to seal the boat and paint it if i pull the sealer off when i beach it. then my rivets will start leaking again. the undercoating would be applied on top of the final coat of paint.
