Guys
I need to put my 1970 GNC stepside into service. I need to use it in my Handyman business to haul supplies and such. Being a single sidewall bed I am worried about dings and dents. Has anyone used a spray on liner or know of a bed liner to help protect? This truck is a low milage original rust free truck and I'd like to keep it that way. And no I cant afford another truck I have to use this one.
