Socal Truck

"Top-notch product and application process. We've compared it to Linex and Rhino Liner, the way the bed liner sticks and holds up to wear and tear is great in the long term. Texture is finer and it doesn't need to be overly thick in order to have the same strength as its competitors. Cost wise, the lack of franchise fees end up helping the customer in the end. We've had nothing but happy customers by applying their spray bed liner."

"Mil+Spec spray in bed liner is one of the nicest and most clean looking bed liners on the market! I was using another product before my work switched, and I’m so glad we did! Phillip who works for Mil+Spec is the best guy to work with, on top of ordering material to give tech advice over the phone. So glad I was able to be trained the best in the business! You won’t regret spraying Mil+Spec bed liners!"
