spray on linings on boat bottom?

[coolbeer]

does anyone here know anyone that has done this? put Rhino lining type liner on the bottom of a bass boat. Ive heard of it, but I cant I find anyone that has had it done. wanted to ask you guys if you had.  I want to do it to mine instead of painting it (dont like the color, and im restoring the rest of it) the rhino liner is more durable anyway.

Don't bother.  I did this on MINE and it started peeling after about 4 months of use.  Adds alot of drag also.

Might work better on the inside of the boat.

We did this to a buddys boat a few years ago to stop leaks. Spread it out on the inside though. It has held up ok and made the boat a little quieter.

I've applied it on the bottom of a 1989 Colman Crawdad, the jon is made out of PVC plastic and  it adhered well. It would eventually peel off/scratch/dragged off so I applied it every spring. It more or less  just help preserve the old boat.

Don't know if I'd use it on the outside of my aluminum, but I like the idea on the inside to quiet bumps and banging down. I ended up fitting it with work foam flooring.

I have heard and seen it done to many boats on the inside. Never on the outside of the hull. It dose add some weight.

Did put the do it yourself roll on liner to a trailer. Made it very easy to walk on. no more slippy rails. Stopped the rust too.

Rough sand entire bottom and 3 up the side then paint it with fiberglass resin. This will form a slick surface that will produce less drag, slides on the trailer easier, slides through weeds easier, will not peel, lighter than Rhino liner and numerous other advantages.

Spray on liners like Line-X or Rhino Liner will add a lot of weight to your boat.

Catt, how do you get resin to stick to Aluminum w/o peeling and cracking off?  I've seen people try this but have never seen anyone be successful.  My boat had one of these patches on it when I bought it, it was all but falling off.  That crack is welded now.

LBH, aluminum is too slick for fiberglass to adhere to; while you don't want to remove a lot of metal you do want the sand paper to make small groves in the metal. If the resin/hardener is properly mixed and applied in a timely manner you should not be experiencing cracking. Most problems people have when applying fiberglass is operator error, there is a technique to properly applying fiberglass but it is not that difficult to master.

Far cracks in aluminum I always recommend welding over any type of patch but again there are techniques required to achieve proper results
