It's a pretty straight forward procedure, there are steps outlined by Tushar in an older thread. The hardest/most tedious part will be to stick the plastic bags on the back of the pad. Just can't apply too much at once, otherwise the paint will run.
Thats the only thing I did wrong, I have also colored an older ayrtek (Was green originally, purchased from CD) to Blue and was a much better job...guess I just got over confident with the pads
....contemplating removing the color off the pads and re-spraying but don't have the time to do the research or put in effort at the moment...
