Rhino Liner on Trailer?

[Double Overhead]

I have a few estimates to get my trailer repainted. I was wondering if anyone has seen a trailer that has been Rhino Lined instead of painting. My friend works at the "tuff-skin" (like Rhino Liner) and could probably cover the trailer for about $100 less than a decent paint job. The prep work is less and it should be immune to the elements.

My other option is to grind the old paint off and cover it with rust- oleum. Any input is appreciated.
