I know this is an old post but I'll throw in a vote for Line-X
I searched all types. A local place was installing a off brand spray in linear that was junk. The only 3 name brand ones are Arma, Line-X and Rhino. My dad has Arma in his truck and it is lifting in a few spots. I heard Rhino almost dries rubbery then fades eventually and lifts to. I heard little complaints about Line-X so I had it installed and love it!
