Stop in for a cup of coffee

Real car paint does work on plastic models, I have done it before.
However you have to do really thin coats to keep the solvents low.

I have messed up a few kits with urathenes but it can be done and when it comes out right, the shine is out of this world
When I built the Chrysler Turbine I ordered Turbine Bronze in real car paint. Unfortunately got base/clear by mistake so it was a double challenge getting it just right. It came out nice but I would be sure not to do it that way again.
