First time painter needs help.

My recommendation, don't use HOUSE OF KOLOR if you are new to painting.

I noticed you said you will be painting one panel at a time. If that's your plan, DO NOT use a metallic, only use a solid color.

You will end up with a car where every panel is a slightly different color.

You want something cheep, forgiving, reasonably good, and available locally. Available locally is key. When you mess up or run out, like you will painting for the first time, you don't want to be ordering paint.

Use this, I just painted a truck with it a few months ago and it turned out very well. You get it at NAPA.
