I have Rhino Linings...Started to peel up in places due to improper prep. Six years later, they actually resprayed after me stopping in to have them take a look. Lifetime warranty if it has the tag or original receipt. They resprayed it thicker this time 1/4" thick. I do also have a rubber mat that is thrown in there too. Choose which you prefer, I don't know enough about Line-X, but do like the way it looks.
