I did drywall tape then coated it with truck bed liner, I had to do 4 coats so the drywall tape was covered a little bit. The stuff I bought took about a week to fully cure, but it works awesome so far, my body is just super scratched up and has two spots on the front where the nuts on the ends of the shock mount are hitting body.THinking of spraying my Typhon with bedliner spray this weekend. Any advise? How many coats? Others done it? Works?
