Do you want to paint it? if so get some kryon fusion paint for plastics and have at it. Disassemble it first though.

sand it first then prime if u want then paint and clear coat.

1st thing you will need to do is carefully take it apart, put the small pieces in something you wont lose them zip lock bag, small container that closes.

2nd want to sand it with 600 grit sandpaper
I wear plastic gloves when handing,
wipe clean, after sanding

3rd Prime with primer or adheision promoter if your using krylon I use Rust-oleum automotiive primer

4th after primer has dried or cured for 24 hours wet sand it with 600 grit or 800 grit, let it whip it down with cloth or paper towel let it dry for a couple of hours before painting . you dont want to sand the primer off or sand thru, sand enough to take ruff edges off the paint

5th spray with krylon or Rust-oleum paint, let it dry over night wet sand with 1500 grit, wipe down with paper towel. let it dry

6th spray another coat of paint, let it dry over night ,wet sand again with 1500 grit wipe down with paper towel let it dry after wet sanding

7th everything should be nice and dry and even look kind of dull looking at this point, clear coat with the same paint you used to paint with, or you could ruin the finish. might crack peal or lift so becareful what you use.

8th, If you wanted to you could lighty sand the clear coat by wet sanding it with a finer grit sand paper like 2000 grit sand paper, and repeat wipe it down let it dry and spray a final coat of clear coat you shouldnt need to buff it or anything, let it dry for 2 days or so before re-assembling the face plate back together, you can use hot glue to re-assemble the power buttong back on, and the metal tab that holds the usb door on. good luck hope this helps out
