Re: Raptor Bed Liner Kit for aluminum hulls?
We do not recommend using bedliner products directly on the aluminum for two reasons..... we have had reports of separation from the aluminum and any future repairs will be a nightmare.
If you are using it to prevent leaks.... go with a gluvit treatment instead
The job of making a riveted hull water tight and last is impossible, when considering vibration, flexing, and the fact that the runners that strengthen the hull are impossible to get inside of unless you can shrink yourself to 1/8 of an inch. When two pieces of aluminum are laid together and then riveted, they are bound to leak at some point. I'm not criticizing the design, movement and flexibility are necessary under the conditions that boats and aircraft go under. Going around every rivet and every lap joint with a product that sets rigid will eventually fail (my opinion
). Today's technology is Superior to that of the day of riveted boat design of the 70's. If the engineers get together and come up with a solution to once and for all, make a durable, polyurethane product that will stick to aluminum, under salt and fresh water conditions, that market would set a new trend for aluminum hulls all over the world. Maybe prep work is all that is needed to make current products work. The object is to spray on a product on the outside of a hull that will make it water tight for ever.
I ran across this in my research...
