Yes, I know most of the reputable paint companies really want a 2k primer or wet on wet 2k sealer over this type of etch after some flash time and they also like a certain amount of mil. over etch prime. I personally would recommend getting a cheap hvlp gun and put some black epoxy down first.Then you get two for one this way you get a great corrosion base and a excellent base for the bed liner. I'm going to be trying some of that raptor bed liner on a car at the shop in the near future.Good luck and me know if I can help. Joe
