    Not sure if there is a listed "correct" that I have seen in print. I used DDL9423 which is more of a Satin than anything, which IMO looks correct. There is lots of different chassis paints but I would think in between flat and semi-gloss is the correct look.

    :)Go with 70% gloss and you will be good.Also sand blast everything if you can.

    Just make sure you put on epoxy Before the paint. You’ll probably have a day sanding all the frame with 80 grit. after blasted. Dupont makes an Epoxy in black. Makes it very easy. Putting a Gray epoxy down would not be the best idea.

    How ever it turns out 70% gloss or how it ends up. Can not ever be as bad as the factory. So if it’s to shiney. Be happy. People like it with more shine. But shows everything.

    Didn't DuPont get out of the automotive finishes business? Anyway, when you put the color over epoxy be sure it's wet on wet. I had a real nice Corvette that they waited too long before they shot the color over the epoxy and the paint came off in sheets. You want to shoot for a satin finish.

    Still can find factory packs and my local paint shop can still mix it but it’s super expensive. Last time I got a quart they found a factory quart for me which was cheaper.

    What I do is blow it really well the spray it down with thinner in a spray bottle then blow it again, followed with 2 coats of SPI epoxy sprayed wet then followed with 1 or 2 coats of single stage urethane hot rod black from Autobahn or Sem.

    The SPI Epoxy lays wet longer and will bridge the tooth of the sandblasted surface

    If you want to go the extra mile you can epoxy, let cure,..then hand sand with 220 or 280, fix any pits you want to, prime those areas then follow the above process

    The SPI epoxy has a very OE look by itself and doesn't "require" to be top coated when not exposed to UV,..its very chip resistant also

    oh Yes i forgot. I had a big stainless pump sprayer for weeds in the yard. And filled it with lacquer thinner and sprayed frame down . Zane got it real clean. like Hugger said.

    The Greenish olive color Axalta epoxy what i’d use first. Then put one coat of the Axalta Black. Also you only need one coat of chassis black

    Frames of the late 60’s-70’s were satin black. Plenty of GM Assembly videos on Youtube

    Okay, so what will have a better finish as far as showing pits etc --
    -- Sandblast and powdercoat
    -- Sandblast, epoxy prime, and finish coat?

    Depends on how pitted it is and how deep they are obviously but if your wanting it to very smooth you'll be better off epoxy priming then putting putty and going that route, I've never been one to worry too much about mild pitting but that's just me

    But to answer your question powder coat generally has a thicker film thickness so it will flow over more stuff

    Well, the powder coat guys are saying the powder coating will show more issues, since it is so durn thin. They will also take the epoxy approach, and say it will hide things better...

    I hot steam Jenny my Frame with degreaser and cleaned it before i sand blasted. Play sand for the non pitted areas. Black beauty for the scale areas. Black beauty is very aggressive. But cleans it easier and faster.

    Be VERY careful buying play sand . Condensation in bag. Then pour in sandblaster. Not good. How many of you tear apart a sandblaster. Rather hit my thumb with a hammer.
