Your thoughts on "Full Metal Jacket" spray-in bedliner. Is it a good choice? If not your first choice of bedliners which do you recommend? Thank you for your response.

i prefer rhino...

The best bedliners are made of a blend of polyurethane and polyurea, like LINE-X. Rhino is 100% polyurethane, FMJ is 100% polyurea. Both polyurethane and polyurea give the bedliner desirable properties. For example, polyurethane has 2 to 3 times the abrasion resistance of polyurea and has much better adhesion properties. Polyurea, gives the liner a higher temperature tolerance and tear strength.
