Trailer repair - spray coating to prevent leakage?

Spray-on rubbercoat like Rhino-shield,etc. Lots of commercial outfits out there.

 

I have used the 3M brand with good results and pretty reasonably priced. Just a regular spray can and seals really good.

Here's a link for it: [ame]http://www.amazon.com/3M-Automotive-MMM8881-Undercoating-Oz/dp/B0002NUO5Q[/ame]

 

Check out the nearest Wabash trailer repair shop I use to run dedicated parts for them they have a complete floor refinishing kit that seals the floor. No idea on the price though.

 

A trailer shop near where I live told me about a product called Key Polymer brand Floor restore. Last I checked, a complete kit with filler for gouges, and the sealer was about $400. 1 kit will do 1 53' trailer. It is applied on the inside. I plan to do this to two of my trailers.

My local service guy has a process they use for this. They clean the floor really well,than put resin on the floor in liquid form. Then they spread it all over the floor
and let it dry. Usually they'll put some sand in it too, otherwise it will make your floor real slick. The last one I had him do, I think he charged $600 for everything. That trailer was having leakage problems at the front, right above the drives. And foodgrade shippers don't usually load trailers that have 4 ft diameter puddles of water ! The resin treatment took care of the problem 100 % Best $600 I could have spent on it.

 

....until some dihspit nails a few boards to the floor to hold a pallet or two in place....
