Best paint for Bandai DX plastic? (adhesion/durability)

[David Hingtgen]

My Ozma -29 had its nosecone yellow (top half only), and so the contrasting colors between the halves made it obvious.  "Retro-brite"'d it for days and got it 95% un-yellowed, but it came back already. So I think the only permanent solution is to paint the whole nosecone.  My fear is that the -25/-29 nosecone "tucks into the chest/nose gear bay" during transformation, and it might get scraped off.  I also know that Ozma's  -29 DX plastic seems awfully "repellent" to paint, as it took a ton of effort to panel line and paint just a few tiny details back when it was new.  

I'd like to avoid sanding down the nosecone for adhesion, as I'd prefer to mask around the 'arrow' detail on the nose, and preserve it if at all possible.   

PS---I would much prefer not to airbrush, and just use a spray-can, but would be willing to airbrush if there's some miracle paint that adheres way better than anythin in a can.

The best adhesion will be lacquer paints. Definitely the toughest, but also the most dangerous. You could test on a spoon with acrylic and glossing over with a 2k gloss and I’ve heard that can make the some weaker paints much much tougher. Bassically try beating it up and see how much mistreatment it can actually take. And of course if you want a dull or satin finish after you can add that on top
