Hello again,
I need to paint a dark piece of styrene with White Polly Scale . What would you suggest for the underCoat? I cannot use Oil based (Health) and PolyScale doesn't make a primer Or do they? Thanks a lot.
Wash the styrene thoroughly in dish detergent to eliminate mold release agent. Then spray a couple light coats of grey primer from a spray can. And I do mean light! You don't need 100% coverage, just enough to provide tooth for the Polyscale.
OTOH Scalecoat make a primer for plastic that protects the styrene from their paint. It's also good as a primer for other paints. You might want to try that.

Yabbut the OP said they didn't want to use oil-based paint for health reasons. Unfortunate, since this really is the best way (actually the only effective way that I know of) to prime styrene for water-based paint.
I'd suggest to the OP that maybe they can use this method (spray paint primer) safely by just observing some simple precautions: spray in a well-ventilated area, and wear a mask or a respirator (always a good idea for anyone).

That probably rules out the Tamiya spray primer as well, as it is synthetic lacquer based acrylic paint, as it is also a good primer, for a rattle can. :-)
Testors (Model Master) offers a white primer in the Acryl line of acrylic paints. PolyScale and Model Master Acryl are produced by the same company, which is why PolyScale non-rail road colors (green label) paints are discontinued. Snarl.
