    Just wondering if a spray-in bed liner for pick up trucks could be used on a houseboat bottom where hull performance is not much of an issue.

    Ever heard of it being tried before?

    I know that turbo liner put a north river jet upside down and sprayed it 2 inches thick then poped off the shell that it made and put on a 50 hp outboard and ran it in the snake river to sell their product to dealers. very waterproof. If that is what you are looking for.

    If you are looking for something to keep growth off the boat I'm not sure that it would work because it is a very rough surface and algae etc would grab it easily.

    Durability-wise it's hard to beat. We use it on the inside of our hulls instead of gelcoat or paint.

    when they spray it on they do not have to do the texture. It would be very smooth and the growth would probably just wipe off easily.

    All of the hand applied truck bed coatings are polyurethane, which makes them very good as an anti-fouling coating. They stick very well too, though you do need a very clean, slightly toothed surface as a base. Depending on formulation, most can be applied without a texture surface.

    thanks

    Thanks guys! The above is very useful. I am building a trailerable houseboat and was concerned about the abrasion during the frequent launching in very different waters. You guys answered my doubts. 'preciate it.
    Spraying without texture is great info.
    Regards

    I would not use any polyurethane submerged...

    Well I will add my 2 cent I would look for a co. that sprays Polyureas, check www.specialty-products.com with a good spray equip as from Gusmer it can be layed on slick. We spray the botoms of Drift Boats and it works well. Fritz

    I've been testing these products for a few years now and I can tell you they stick very well and have good anti fouling properties too.

    good morning Par, ,what products and equipment are you spraing and how thick, I am spraing with a Gusmer 1818 and D Gun, on drift boats 1/8 to 1/4 thick. Anti fouling I have not checked out, my hunch is to prssure wash the lower hull, to get the growth off. Fritz

    Minimum coating thicknesses are 30+ mils and pressure washing works well to remove scum and fouling.

    Laminates and Rhino Liner

    One would think laminates frames would be far more sturdy and waterproof if sprayed with Rhino Liner.
    There are several laminates which can be created and shaped more easily than the present.Not only that,they can be spaced closer together to provide more safety for cruisers and sailboats.
    The building industry is also seeking cheaper laminates for structures,and future structures may have ectoskeletons which have been proven in nature.

    It would be nice if you made some sort of qualifying comments so we would know what you're trying to say. It sounds like you're attempting to say that laminated wooden frames could benefit from a truck bed liner coating.

    As far as spacing, this is determined for the strains expected to be encountered. Closer spaced frames with a lighter planking or wider center to center arrangement for thicker planking.

    Any cored hull shell is basically an exoskeleton. These types of structures have been around for quite a long time in land and marine environments.

    I don't think it would make anything sturdier or stronger except in the long term where it might protect against degradation or rot. Does that stuff stick to wood?

    I don't understand what you're saying about endoskeletons. What sort of laminations can be created and shaped more easily than what sort of present ones?

    If the building industry is seeking cheaper exoskeletons that have been proven in nature, I would be wary of them selling eggshells they claim are turtleshells. ;)
