    Here is the situation. I have a 2000 GMC Sierra that the box has rusted off. I found a replacement for $200 on CL. Before I put the box on the frame I would like to sandblast the truck frame and the bottom of the box. The question is what do I then treat the bare metal with...POR-15, Bed liner, Farm paint..:help:?

    The bottom of the bed, I'd seriously look into a bed liner coating.
    The frame, just a good primer and a good top coat with a hardener in it.

    POR is recommended to be applied over heavier rust as it penetrates and hardens like steel, it has to penetrate to stick, read up on it before you apply it to bare metal, other than that, an epoxy primer and two part paint is as good as it gets

    im doing a 2002, needle scale the heavy stuff, spray a couple of coats of eastwood encapsulater, followed by 1 or 2 coats international oem black machinery enamel.....east wood also has stuff with tubes to spray inside the cross tubing and box part of frame

    tried the sample cans of por-15, was not impressed,

    It's all about the two prep chemicals with por 15. If you do that perfect then it will never rust.

    Thanks for the replies, I think I will POR the frame and the underside of the bed, then use a bed liner product for the inside of the bed and fenders.

    I swear by Bill Hirsch products...same concept as POR etc. He actually developed it for the other companies, left years ago, and developed his own. Look it up...worth a look. You can even call and literally talk to him...although in his 80's one - he will chat with you if available.
