    Paint/coating for frame and flatdeck

    I'm flatdecking my superduty, and need to clean up the frame a bit since it's going to be exposed. Plan is to pressure wash, then wire wheel if necessary, and hit it with...POR15 or a similar product? Tremclad? Something else? I know POR15 needs to be topcoated, any special considerations as far as what paint gets used?

    Then the same question for the flatdeck itself. Tremclad spray? Something else?

    I’ve never had any luck getting por15 to stick. It usually ends up peeling off inside of like 2 years. Rock chips and whatnot lead to it coming off in chunks. If you are in the rust belt, I’d grab a 5 gallon bucket of Woolwax, the black dyed stuff, and shoot everything underneath with that. It makes a big mess, and it makes it impossible to work on the truck and stay clean, but it’s easy to apply and touch up, looks decent, and helps block moisture and salt from getting to the metal and causing rot.

      I'm in the Canadian PNW. I've dealt with that spray on waxy shit and never fucking again. Full marks for effort though! Good to know about the POR15 though.

        We had a POR15 rep come into the shop one day with our Sherwin Williams guy. Laid out exactly what we needed to prep with etc...and the shit still didn't stick. If you can get it to work my hats off to you.
        Whenever there is doubt, there is no doubt.

          If it’s not for you, that’s absolutely fine. I like it though.

          I feel the price premium for the por15 isn’t worth it. I can keep a frame coated in 99’cent rattle can paint for a whole lot less, and in my experience you get about the same life before it needs attention

            What about Monsta Liner chassis saver paint? They used to push that stuff on PBB when they were a vendor there and everybody that used it loved it.

              I may just give that stuff a shot...if they'll send it to Canada.

                I painted the floor and top of the boxes on my service truck with Mastercoat AG111. Supposed to be tough as all hell. I haven't beat on it yet, so I dunno, but it seems pretty tough. Its kinda pricey though. Stinks to high heaven. I brushed it on and it's kinda weird to work with too...

                        Oh also a needle scaler is a must if you have any kind of shit on there that you need to get off before coating it, and I'd buy some Ospho and put it in a squirt bottle and hit everything with that before painting if it has any kind of surface or flash rust on it.

                          I've been quite pleased with Tremclad. I painted my flat deck in 08 and just repainted in 2018. It has held very well considering the minimal investment. I'm another one that has had poor results with POR15. Everyone says how great it is but good old Tremclad works far better for me.

                            How did you paint it? Just cleaned the steel and sprayed it? Rolled/brushed? Actual spray gun?

                              Tremclad with some enamel hardener mixed in and thinned with mineral spirits, through a cheap HVLP gun.

                              8:4:1 I think was the mix ratio I was using.
