I used the POR 15 and exterior Behr paint last year for my bed. Did not mill the planks before application. Used 2-3 coats of POR 15 and 2-3 coats of the exterior paint. All went well and as described on the Mar-k site. To this point (other than my scratches) the treatment has held up great. It went on smoother than I thought it would.
