I don't know if RHINO is better then LINE X, I have never heard of them. Rhino linings can be put on to any desider thickness. I have never seen one loose its color but that is a good question. I think they may be able to do a smoother finish. I am going to search the Internet on the LINE X product line for information.

CAVEBULL, I know a few rodders that used it inside their cabs on the floors. They claimed it was an excellent sound deadner.
