 Spray-on bed liner
I shot the bed of my '74 long bed last fall with ?? liner. Used the college body shop gun and their expertise and it went ideally. It is probably the same as Herculiner but I can't remember the name. Since then I've hauled gravel, sand, flat rocks and tree limbs on it. This spring I freshened up the bottom with a pint can I got through a mail order parts house (I don't know if I can give the name here). I just used a 4 inch roller and plastic tray. Took 40 minutes and looks like new again. No more sand, gravel and rocks so it should look fine for a long time. Unfortunately I learned the hard way what happens with those stupid *&% bed liners after 10 years. Had to repair the bed with fiber glass roving and matting before we covered it. No problems so far. |
