We’ve seen this countless times over the years at Inyati Bedliners: Sprayed in Bedliner installers who spray over their customers bed hardware including the bed bolts. It only takes a few minutes to remove the bed bolts and re-install them after the spray in is complete. We can only guess that people don’t do this because they are lazy, or because they don’t know any better.
It is important to remove the bed bolts, and NOT spray over them because should your truck need any drive train or fuel system work, the mechanic is going to need to lift the bed to gain access. In order to lift the bed the mechanic is going to need to remove the bolts. If your bolts are sprayed over, then the mechanic is going to use a hammer and chisel and chip off the liner to get to the bolts!
We get a lot of calls from mechanics and body shops asking for advice on how to repair this damage, which is not covered under warranty. Repairs of this nature usually cost several hundred dollars
If the original installer had just taken a few minutes to remove and re-install the bolts, none of this would have happened.
