I tried a light sanding surface prep on both capsules. I used Krylon white primer on one and shot the other with Krylon Gloss Black, no primer. I'm going to use one of these on an Egg Crate and the other to top off a 1340.
Wish I had the original Centuri parts that were molded in black .....

I know this is three months late, but I just spotted this product reviewed in Model Railroader magazine (Yes, I confess, I am seeing...other hobbies...  ). This appears to be just what you're asking for (or, You asked for it!)...
Specialty Performance Products SXA 1050 Plastic Adhesion Promoter, sold through PPG dealers. About $15 for one can. You spray a good coat, or two thin coats, and allow to dry about 15-20 minutes. You can then spray on any good enamel, and it should stay attached without chipping.
The reviewer sprayed it on some HO scale locomotive handrails before shooting color, and it was able to take a lot of abuse like flexing and bending without chipping the paint. It also stood up to scraping with a fingernail. |
