painting over powder coat

What is the best way to spray paint over an already existing powder coat. For instance: My CAI is powdercoated red, and now i want it black. I want to use spray paint to do this. Should i sand first, or just spray it on? Are there any other techniques to make it turn out better.

Prep it as you would any other thing you have spray painted. Sand it with a red Scotchbrite pad or 400 grit sandpaper.Then take some lacquer thinner and clean it thouroughly with a paper towel.Now take a tack rag and remove any lint or dirt you have left. Now you are ready to paint it.Do not touch it with a paper towel , a rag, or your bare fingers until after the paint is dry. It should be hung up in such a way that you can get to all areas without moving the piece. Allow it to air dry for an hour before you touch it, then bake it at 200 degrees for 10 minutes, or leave it to dry for a day. I do not think that 200 degrees will remelt the powder coat, and it will somewhat harden the paint. Just don't use your house oven as the smell is overwhelming and you will not be able to cook in your oven for some time(Don't ask me how I know!). Get a junk oven that works and use that. I oven baked Dupli Color engine enamel over Scotch brited chrome engine pieces 2 years ago and the paint hasn't flaked or peeled!

I've painted my CAI red again because it looked like it needed some newness to it and it came out fine. I'd definitely light sand it a bit before applying new paint.

Have you thought about having it powder coated again?
