There were 4 offerings in my area:
"Our LINE-X® STANDARD black bed liner is $575.00*. LINE-X® PREMIUM couples the abrasion and impact protection you already trust with our STANDARD formula bedliner with the UV protection a bedliner needs to keep its’ luster. Like a sunscreen, LINE-X PREMIUM safeguards your truck bed from solar burnout and fading. Visible damage from intense UV rays can happen fast. Don’t leave your truck bed exposed, get LINE-X PREMIUM! This can be added to any LINE-X STANDARD bedliner for only $150.00*.
The best just got better. LINE-X has improved spray-on bedliner protection at the molecular level. LINE-X PROFESSIONAL uses a pure polyurea technology that combines strength and flexibility to create the toughest bedliner on the market. 300% tougher. LINE-X PLATINUM is the total bedliner package — toughness, durability, and UV stability. LINE-X PRO is $750.00* and LINE-X PLATINUM an additional 150.00*."
I'll have a tonneau cover and park in a garage so the UV coating wasn't important to me. I went in wanting the Professional, but my installer pushed me away from it and towards the Standard; said the Professional was overkill for a 1/2 ton and he really only uses it for contractors that really abuse their beds.
