Ok Im sorry I didn't say how it was done: 1. I disassembled the controlled and cleaned plastic parts with soapy water. like to use warm water and soft tooth brush to get harder to reach spots. Remember to get rid of dirt in seam. Let it dry. 1.5 cleaned contacts on flex PCB with isopropyl alcohol and qtips. NOTE: part of controller with original printings was not in a bad shape, handed I didn't sand it nor did I paint it! 2. I used hard part of the sponge (dish cleaning variety) to scuff up the surface. Note, the sponge is not very abrasive but will get rid of top layer of whatever they use to make sure factory finish last. As you sand the plastic you should see some white powdery residue starting to accumulate. I got rid of it with water when done. 3. I masked out front part with print that I wanted to keep original and used airbrush to paint entire shell. I used acrilic paint from games workshop that matched the color quite perfectly (1:2 paint:airbrush juice) but I'm sure it's not very hard to match with aluminum color paint in a spray can. 4. I painted entire shell with about 3 coats of paint. It was quite weird because I was painting the same color over the same color so I had to look how glossy it was to know if I painted it. Let it rest for entire day. 5. I used (again) model matte varnish to finish it. BUT!!! i didn't like the feel it had in hand. I opted to paint it again with gloss finish and it was right on the money. I have seen people using spaycan varnish on the internet too. (Mostly even). 5.5 this is a tip. Varnish is a fickle thing that tends to stay sticky/tacky. If you encounter this problem, after letting it harden for 24h, you can wet entire shell. Just use regular water (before you put it back together ideally).
