Been retired for a little more than 24 hours, upon ending my almost 31 year association with my employer I went out and bought a new GMC Sierra! Now I'd like a spray-in-bedliner. Rhino or Line X? Or? It's going to be black. Pros/Cons? From the research I have done I've discovered that Line X goes on hot, thinnner than Rhino, but follows contours better. Rhino goes on cold, thicker, more sound deadening, easier on the knees.
