Where do you live? What's the weather like there? Reason I ask is that ideally, you want to spray paint out doors when the weather is around 70 degrees or so.
I'm in Phoenix, so kinda hard to do that right now. We're hitting 110s during the day, right now.
As for the paint, I bought some today, but have yet to start the painting.
Primer= Tamiya fine surface primer (white)
Paint= Rustolium bright coat gold metallic finish
