ok so i wanted to try the bed liner.because i need durably. so is there anything i need to know before applying it do i need to primer sand with a low grit paper.
I just used a Duracoat kit from Discount Autoparts. Cost about $50.00 and had a gallon of bed liner, tray, brush and roller. Worked real well, no complaints. Put on three coats since it's in the bed of my Avalanche. Covered, but not water proof.
Definetely put it on outside if possible. The stuff has some super fumes and u'll get high as a kite in no time. Whoot:
Also, don't forget to coat up to the edges of the box. Your fabric will overlap the edges.
