    Gotta get up to speed, I'm an old school nitro lacquer guy but haven't sprayed a car in 25 years.

    I have very little experience with the new urethane/epoxy products. I'm looking for a good bare metal primer, perhaps high-build for finish sanding????

    Any good sites to walk a guy through to the other site of the forest?

  2. Check out Southern Polyurethanes website, good info and good stuff.

    Metal and filler work 1st. Well etched metal with a metal prep rinsed and blown dry, should look "bluish-gold" when done. Follow with 1-2 nice coats of epoxy primer and allow to flash for 45-60min depending on conditions. Follow up with a good 2K type of primer, sometimes adding 15-20% reducer for a nice smooth finish. Kinda the same as the lacquer days with the exception of epoxy instead of the old zinc-chromate. Some 2Ks are just fine over well etched steel. The epoxy is more of an additional corrosion inhibitor and good for old metal, like what most of us are screwin around with. Good luck, from another old lacquer guy...

    I've had very good results for several years using Valspars' Direct to Metal primer . It has good build properties , sands easily and does'nt shrink back. Good luck.
  9. i've always used 5-star extreme direct to metal 2k primer. you can mix it in 3 ratios depending on needs.
    good build and coverage, sands pretty good too.
    i've never had a bad experience with it here in southern california.

    I'd second that with U-POL 2k primer. Not a bad price range for today's material costs.

    need louvers ?

    I don't see the most important bit of info about shooting todays stuff... A DAMN good respirator! Not kidding at all, the little 3M dust masks that we all wore out in the driveway shooting lacquer will kill you with the new stuff. The first couple of times I shot the new stuff I thought "hell, I'm out in the driveway, just a dust mask will do fine". Now I have an allergy to urathanes the puts me down for a week if some one opens some within ten feet of me. Careful!

    Damn right. All this new bullshit "enviromental" paint will kill you faster. 25+ years ago a kid that had a shop next to mine was coughing up blood after spraying emeron outside with out a mask

    The old school acrylic primer is still available in good brands, PPG, Dupont, etc., if that's what you are comfortable with. Thin with lacquer thinner as thick or thin as you want, leave it in the gun and it won't set up, no hardener. Just like the days before the new normal. Let it dry thoroughly (as we used to do) and with a proper sealer you can use the new fangled paint over it. Or depending on your project, just complete it in lacquer as you used to do.
