Truck parts prices change partly by supply and demand just like anything else. It’s been my observation that parts prices and availability for Chevy, Ford and Dodge trucks have been such that driving old trucks “forever” worked well. Sheer numbers of these trucks on the road guaranteed a supply of used truck parts plus a demand for new parts too. However with the closing of many parts plants, doesn’t it make you wonder where the parts will come from to keep older trucks on the road.
Spray on bed liners have several advantages over other options. Now these are offered as options even on new trucks. Usually for a new truck the application will be done by a local franchise of one of the big name liner companies.
Spray liners are after all really a paint application over the existing bed paint. But it is special paint. Partly it is special because it dries and cures very rapidly. The paint usually is a two part product mixed right at the spray gun. Engineered to cure fast, that means the time to get the project done is very short. Usually that means the truck only has to be at the applicator just a day or so.
My guess is that at some point in time some pieces of the truck parts system will just report that the parts requested are not available. Already my review of the GM online parts site shows it stops well short of the 1976 model year. That probably means a decision to drop older parts inventories and manufacturing has already been made, maybe.
The guarantee that comes with liners is not that the liner won’t be harmed, it is that it will be repaired. Repair just means a respray, that’s all. Another basic feature of liners professionally installed is proper preparation. Like for any paint coating, proper surface prep really is key to a coating that sticks. Scrimp on surface prep and the coating likely will be gone with the wind.
That guarantee you get means the surface prep will get done and it will be done right. Spray on bed liners work so well for a number of reasons. It’s partly because of the material itself used in the coating. But it is partly just the careful application too. The guarantee you receive means the application must be done properly or the dealer will be forced to do it over again.
