I'm thinking of getting a spray in bed liner for my new 2006 Sierra. I have a Rhino liner in one of my older trucks but I was wondering if there is a better product out there? Some people say Line-X is better but I have heard it does not keep it's color well and turns chalky. Any comments?

There is an age old discussion right there.
I had a Rhino put in my 2000 GMC last summer and love it. I believe most of them don't fade/turn chalky as past formulas do.

They key is the prep and application of the person doing the work.

Here is my liner a few days after installation. I also bought a new set of GM bedrail caps:

Linex here. It has been 6`months since I put it on 2005 Duramx. No fading so far and I love it.

I went with a color matched PermaTech. No fading and I get a lot of good comments on the color match of my 67 medium blue iridescent.
