rino line is sprayed at like 100 degrees and line x is sprayed at about 170 degrees.
the line x will come out smoother and better looking and adhere (spelling?) to the surface better.
forget about Rino line
This is only partially true. I work for one of the major suppliers for bedliners and I can tell you that the best advice is to go to a shop that can demonstrate prodcut knowledge and quality.
Line-x did a great job of getting more consistentcy in the bedliner application market but you can still get a crap job if you go to a hack shop. The brand isn't as important as it used to be, the product has become more of a commodity at this point in the lifecycle.
Take the time to visit the shop and check it out. See their work and see the level of cleanliness and organization. This will be the best indicator of the quality you will recieve.
And YES, you can spray the composite bed but it does require special attention in order to get the best adhesion possible.
