Make sure you use a water filter on the compressor and then use a disposable moisture filter at your gun. You want dry clean air flowing through your gun! I live in Florida and when I let the air out of my compressor and filter it pours out water. Your will also need:
1. Good NIOSH respirator
2. Wax and Silicone remover
3. Good sanding blocks
4. Lots of sandpaper. I get mine in rolls from Eastwoods.
5. Patience
6. Patience

I am about to tackle the labor intensive work of blocking my entire truck. Can't wait! I want to paint the truck myself but I need to figure out how to build a decent garage paint booth. Have you thought about that?
