Just using for comparison, having never used Rhino or Line-X. Got SEM at local paint store, tinted to match truck, 2 part mix. Kit came with a spray gun similar to undercoating gun. 1987 F250-I rolled mine on because was working outside and was windy. Being tinted it does show scratches. Going back to original post I would recommend a bed rug for what the OP needed. I would have gone to the BR for a few hundred more $ if I was aware of it at the time.
