I'm a LINE-X dealer. Allow me to address some of the issues.
Rhino and LINE-X are not the same products. Rhino is 100% polyurethane and LINE-X is a blend of polyurethane and polyurea. LINE-X literally has more than double the tear strength of Rhino (LINE-X 304 pli, Rhino 145 pli). LINE-X does not need to be as thick as Rhino. Would you rather have 1/4" of aluminum or 1/8" of titanium? The thickness of LINE-X should be about 3/16" on the bed an a little less on the sides and tailgate. If you want more, talk to the dealer.
Rust is the enemy. All rust must be removed as best as possible and if rust was present, I always use a special LINE-X primer called XPM.
LINE-X can easily be repaired and if you have a LINE-X bedliner, you have a limited nationwide lifetime warranty. Now, if you abused the bed, like dropped 2,000 pounds onto the bed from a three story building, you are not within the limits of the warranty.
There are several ways to keep LINE-X always looking brand new:
Good: Apply Just Once several times a year (
www.justonce.com). 303 Aerospace is also good.
Better: Have the dealer apply Ultra Shield. US is a one time application. It keeps the liner from fading.
Even Better: Have the dealer apply Dupont Nason. It's more glossy than Ultra Shield, thus better looking.
Best: Have the dealer apply LINE-X Xtra. Xtra is a darker black, glossy, contains Kevlar Micro Pulp, applied like a topcoat but migrates into the bedliner, and is guaranteed not to fade or lose its gloss.
If your LINE-X has faded, you can restore the color buy scrubbing the snot out of it with a stiff brush, water, and auto soap. Let it dry and then apply some Just Once or 303 Aerospace.
A truely unique LINE-X product that's used by the military is called Paxcon. Paxcon has been sprayed inside the Pentagon, Federal Building in New York and inside US nuclear submarines. Check out the site:

Also, the LINE-X bedliner product (XS-100) has been applied to about 50,000 bullet proof shields that the military uses. This soldier's life was saved by the shield and he is presenting it as a gift to Donald Rumsfeld. Notice the LINE-X coating.

Speedliner (and Superliner) are solvent based brushable polyurea paints. Since they are paints, they do hold their color better, but they lose their gloss and they are not as durable. Also, Speedliner and Superliner must apply an adhesive primer first because their product does not have good adhesion properties. Speedliners website states that after only 2,000 hours (that's less than 3 months) the liner loses 20 to 29% of its gloss. Here's the link:

Here's LINE-X with black LINE-X Xtra. This bedliner is guaranteed to always look this good.
