I've gotten myself into a box truck conversion and the box is made from 3/8" FRP panels. There arnt any ribs to mount anyting to on the inside so I want to mount 2x2 wood batons to the inside of the box for insulation and to mount cabinetry to. My question is, does anyone have experience with FRP panels and what is the best adhesive to use? Should I use the FRP cement that you can get at the big box stores, or should I use somehing like Sikaflex 252? Or should I bolt the batons though the FRP? Thanks
