I used plastidip on mine. It costs about $3 a can at walmart, and for my 75g I used one and a half cans. It peels off whenever you feel like changing it, with no damage or residue. I chose black but it comes in almost every color. It says to do one layer at a time and allow dry time, but to be honest I just sprayed mine til looking through the front it was a nice solid black and let it dry overnight. There are few small ripples on the back, but they aren't visible at all through the front. I just tapes some bags on the sides to prevent over spray, but I wasn't too worried as it peels off anyways
