i think i just installed a bedliner in a drug trafficker's truck. he had false side panels and false bed rails that lifted off to reveal cavities in both sides of the bed. he said he wanted me to spray liner over the lip so when anybody lifted the bed rail cap slightly they would see only liner and assume everything was on the up and up.
p.s. a coming onslaught?
I've got some step rails that need to be put on.
let me know what i owe ya.
