Before they started offering the SR22 in "raspberry" and "lilac" I stopped in at our local powdercoating place in town here, but they said that they wouldn't do the Cerakote coating on my wife's for me. They were too worried about heating up the plastics on the gun to the temps needed to "cure" (or whatever it's called) the coating. I took a printed copy of this photo with me, I'm assuming that it's the photo you found:

The lady who had that one done had the photo up for a while and then got all weird about it and took it down. On the internets though... things tend to survive and pop back up even after you've taken them down. I'm not sure who is hosting it, but it probably doesn't belong to them. Just saying.
If it was me (and this time last year, it was me) I'd look into getting the raspberry or lilac editions and save yourself a ton of hassle. Or even easier, head over to http://www.tractiongrips.com. A couple times a year he offers pink. They're easy to install, functional and look pretty darn good.
