petzoldt's paint

I have a bottle of candy apple airbrush paint from them, and i'm wondering what kind of primer i should use under it, as when i tested it melted the automotive laquer i thought to use under it.

Here is the link to what i'm talking about. And when i spent more time sleeping than listening in the german class :grinno:
