I thinking about painting a few of my interior parts red. I dont have any idea how to go about doing this so hopefully someone can help me out. I dont want to do too much. Im still not sure if im going to like it or not but i figured i can always change it back. So far i know for sure i want to do the air vents. Not sure what else yet. Any recommendations?

I also want to do the gauge needles. How would i do these or are there some i can buy

You need to get paint specifically made for plastic use. If you are painting any of the softer plastic/vinyl parts inside, you will need a more specialized paint that has a higher flex additive and adhesion promoters.
