i think it’s very rare to have to remove a pickup bed for service other than an accident at which point the bed is getting replaced anyways.Twice as thick... and they don't spray over the bed bolts.
I‘m less comfortable with a ‘tech’ at line X removing correctly torqued factory bolts and then replacing them for no apparent real world value.
My 2011 F150 was Line X, 2018 F150 was factory. Go factory if ordering. Also recommend the rubber bed mat on top of spray in. The Ford bed mat is a perfect fit.
