Make sure you also understand the warranty. Linex offers a blanket type warranty that covers all the franchise locations. If the shop that sprayed your bed goes out of business you are still covered at other locations.
Rhino on the other hand does not offer this type of warranty. If the shop goes under you have no more warranty. I went the Linex route due to the warranty and IMO is a far better product.

 

Actually, Rhino has now copied LINE-X's warranty. However, I have heard that Rhino dealers can participate or not participate in the warranty program. I don't know if that's true or not.

I agree that proper surface preparation is extremely important. However, there's more to the story. Even if the surface is prepped properly, some bedliners will get better adhesion than others. The best is a heated/high pressure system because the high pressure (about 2,000 psi) forces the product into the surface profile and the heat lowers the viscosity which also allows for better penetration. LINE-X uses a heated/high pressure system and does not require a primer. The brands that use low pressure or no pressure and are sprayed at room temperature do not get good adhesion (or I should say "as good"). Some of them even have to first use a primer because the bedliner product won't stick well at all.

 

3rd Rhino, average 4-5 year beat up time. Never a problem. (rocks, pallets, etc) Things stay and don't slide like the others. Just make sure they leave the drains open.
