I applied Herculiner to all of the plywood doors & hatches on my rear seat area storage it adhered good and seems to holding up alright. The secrete to getting a nice even coat is their roller, I bought a 1 Gal. kit that had 2 rollers in it. I did a roll on bed liner job on a Trooper I was going to sell and it had had a vinyl trim on the lower 3rd. The Herculiner went on very even and look great, I had over 1/2 can left but had used the rollers so the next job I tried to buy more of the same rollers and ended up with some POSes that would not even roll so applied it with a brush, not near as even of a coat and I have yet to find the right roller.
