lineX
 

Had anyone ever done lineX on the inside of your Cherokee? If so what can I expect

Not sure about line-x specifically but lots of folks use some form of spray on bedliner.

i have Line-X in my bed. super durable, gets hot when in the sun, sometimes can be hard to keep clean, keeps cargo from sliding.

Is it better than having carpet? What other types is there besides lineX? Would this be a weekend do it myself project?

Its better in the respect that it doesn't hold moisture like carpet. Much more than that is personal preference.

There are spray on and roll on types. Duplicolor is one brand.
