i'm wanting to put spray on bedliner on my new truck and did research on line-x, rhino, speedliner, and others. i have decided to go with line-x or a bed rug, but probably will stick with line-x. i read the temperature must be warm outside before spraying to ensure the spray on will set in well. it is about 45 degrees here in oklahoma, and i contacted the dealer and they warm up the bed before spraying. my question is, if it's okay to spray now or am i better off waiting a few months? also he mentioned they have an optional product called ultra shield that can be added for 40 dollars to protect the fadding, is this worth the money? last, any recommendations of shops to go to in the oklahoma city, norman, or stillwater?

thanks for any advice
