I have a 1992 Chevy sitting out it the yard with a plastic bedliner and there is not rust under it. I know that what everyone says but I have not experienced it and have been using them since they came out. The cab corners rusted out first. I have the GM one in my 2004, I only like the GM brand as they fit much better and have the GMC logo molding in.
The trouble with the spray-on's is that they are permanent. Also, they depend on the quality of the application. I have seen a couple over the last several years that have not held well and were coming off. Whenever the dealers see a truck come in for trade with a spray-on, they go to work to make sure it was not a contractor/logger type truck as they will often do that to hide box damage. Last I was looking that was the first thing I was asked about, spray-on liners are a 50/50 at sell time. Some want and other do not, so dealers go by experience and if they are deterent, your value will be less. Watch out buying used truck with new spray-on, they could be hiding something.
Do what you want but if you are not doing heavy hauling, I don't see the expense of a spray on being worht it. Expecially when you go to sell and the buyer does not want it, you can't take it out. Whats more the buyer is not going to give your extra for it, you won't pay extra so don't expect others to. In 15 yrs the truck won't be worth a dime more if it has a liner.
PS-I have also been truck onwer all my life, first new truck was a 1972 El Camino SS and then a 1975 GMC 4x4. Today a 2004 GMC.
