      I laid a nice coat of Xtracolor Boeing Grey on the wings of my 1/144 Authentic Airliners 727 and let it dry for 3 days. It looked great until the back of a fingernail accidentally brushed against it and it scratched clear through to the primer. Suspicious, I then applied a strip of Tamiya kabuki tape to another area on the wing and pulling up the tape removed a large patch of paint. I had primed the model with Stynylrez before laying on the Xtracolor; having had terrific results using Stynylrez under Mr. Paint, Tamiya, and Gunze Acqueous paints, I was expecting similar results under Xtracolor. Unfortunately, it seems the Xtracolor had no intention whatsoever of bonding with the Stynylrez. I'm now in the process of stripping the paint, and likely stripping the primer as well.

      For those who have successfully used Xtracolor, what is the best primer to use under it? Any steer you can provide will be greatly appreciated.

      Much thanks-
      Ken A.

      If your previous experiences were only with water-based acrylics over Stynylrez primer, that may be the clue, as they are similar types of paints. Xtracolor is an oil-based enamel. Mixing paint types (and brands) can sometimes lead to disaster. I always use an automotive lacquer primer as a substrate, which allows any type of paint to be safely applied over it. That said, my personal choice in overall finishes never involves any water-based paints.

      My experience, for Authentic airliners kits and other resin forms, Tamiya primer, that's it.
      Recommended by Kurt long time ago, no issues.

      All the best,

      Tamiya is nice and doesn't fill details, but you can't spray other brands of lacquer over it, plus it's
      very expensive. In the US, try Harbor Freight's lacquer-based auto primer; $4.99/can... cheap!

      Why no other brand lacquer over Tamiya, have you had bad experiences with specific combos?

      I'll +1 the Tamiya on AA kits, I've always used them and it's worked well.

      Yes. I made the mistake of spraying some Dupli-Color automotive acrylic lacquer over some well-dried, Tamiya spray lacquer, and it totally alligatored. I had to bead blast the whole mess, and start over. Once burned, twice shy!
