Teardrops n Tiny Travel Trailers

In planning my tear I am trying to decide what to do with the bottom, underneath it. I am thinking of having it rhino coated (you know, the stuff you can have sprayed in your truck bed instead of a liner). Do you think this would work, or would it be too heavy?

I think it would work just fine, but it's expensive. The roofing aphalt emulsion stuff works great and is only about $5 a gallon, and that is more than enough to do the bottom of a big teardrop. Just my opinion.

And $5 for the brush, which you throw away...... I wouldn't bother with anything else...... after a day you can handle it and it works fine.
