Can I use Tamiya Polycarbonate Paint on Plastic parts, such as the rear wing, and mirror housing, of my Subaru STI. Many thanks. Flyfisher

Needs a primer. Normally the PS just drips off the plastic. And it won't be so shiny as the gloss TS

You can, but like Waterbok says, it will not be glossy and most likely not look good.
You can add TS gloss on top of PS, but then it's easier just to use proper TS paint.
