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).

You were wrong, and I'm man enough to admit it.

: : 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? :     I think the best primer is still the Floquil grey primer, but you say you can't use that.
    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.
