Step 2: Prep Work
First, wash the car and all pieces to be painted real well to remove any loose dirt. (Pic 1)
Next, remove anything from the car that you can, this will help avoid the possibility of getting paint on things you don't want it on. This is to include headlights, tail lights, trim pieces and more depending on the car. (Pic 2) I took off my bumpers and side mirrors as well. The bumpers because they have a few "style indents" in them that I wanted to be able to paint in a horizontal manner as opposed to vertically while mounted to the car. The side mirrors I painted as well so having them off of the car made that a lot easier. I also removed my body kit pieces as not to drip on them while I painted the car itself. I guess what you need to remove will be personal preference depending on your painting style and needs. Once everything is removed, you can really get to work.
Everything that is going to be painted needs to be wet sanded with 600 grit sand paper. This will help to further remove any impurities from the paint's surface giving you a clean slate to work with. Move down to 400 grit if you have a problem area. Make sure to use a sand paper designed for wet use. Once the sanding is complete you will need to look for any spots where the paint has chipped off or the sanding has exposed some of your base metal. If you find any, spray them with a quick coat of the spray primer. This will help make sure you have a nice even looking finished product. It will also help to ensure the finished paint resists cracking and peeling from the damage to the old paint. Of course, if you have any body work you need done, now would be the time to do it.

Any trim pieces that do not easily remove you can tape up with the painter's tape. Make sure to double check your tape job before you begin. You do not want to be in the middle of painting and realize you did not tape something up! (Pic 4)
