Step 2
Disassemble and clean

First off, you are going to have to disassemble your controller.

Step 4
Paint
Now your controller should be 100% ready to paint, if you prefer you can do a primer, but I did not and everything went fine.

I stuck my triggers, start and back buttons on nails in styrofoam. Also I stuck the D-pad, bumper top piece and gray bottom piece into some, just so i could get good paint coverage.

For this step I put painter's tape in the holes on the front(for the d-pad, sticks, start, back and abxy holes) so that when i did my second coat it wouldn't glob up inside the controller. (which is was completely useless because I didn't paint anything while it was together, so you can pretty much ignore this silly step.)

To start you want to put your base coat on (preferably the lighter color). Be careful to do several light coats. Wait about 20 minutes between coats. The first coat may not seem like enough but after 3 or 4 coats, it will be looking good.

After this step, I let my own dry overnight.

Step 5
Apply your design
This is where the razor and painters tape comes in!

For this step, I put the shell of my controller back together so I didn't have to line everything up separately. I placed my design and then after I was satisfied I went and cut the tape at the cracks with my razor. I went for a zebra stripe and it's pretty sweet I would say.

Make sure your tape is stuck well or the paint will seep into it a little.

Step 6
Second color
Now that the design is done, cut the seams and take the shell back apart.

Paint your second color just like the first. Several light coats, about 20 minutes apart.

Let this dry awhile before removing the tape. Carefully remove your design and marvel at your own awesomeness.

(Sorry I didn't take any pictures of it while the whole thing was painted with the tape. I was too excited to finish it.)

CLEAR COAT! I cannot stress enough for you to put a clear finish on your controller. This will protect the paint from chipping and keep it nice and shiny! If you don't put this on the paint will be off before you know it.

The process of clear coating is much the same as painting. Several, quick even layers about 20-30 minutes apart. Let is dry good overnight or you'll end up putting fingerprints into it.
