What is the best kind of red oxide primer to use on a Tamiya Tiger? I want to prime both the metal and plastic parts. Most of the primers that you typically get at your local hardware store are intended to be used on metal parts, not plastic.

I spent a lot of time stripping the old paint off of my Tiger (What an ordeal that was, I won't be doing that again..) I'd like to choose an appropriate primer to use as a base to spray my Tamiya acrylic paints over top of it. I want a primer that will take the Tamiya acrylic paints and not have adverse effects on the plastic parts.

I think some of you guys have used Rustoleum and Krylon primers, which are probably intended for metal parts. Do these work OK on the Tamiya plastic parts without causing problems?

Do any of you guys spray primer through your air brushes, or do you all use Shaker cans?

Lastly, is red oxide the correct primer color for a Tiger that was manufactured in the summer of 1943 (June,July)?
