I've used WD-40 on guns when I was a newbie about 7 or 8 years ago, and those guns still work fine. The cans themselves actually say that they are good for use on O-rings, in fact synthetic rubber is petroleum based. Some mechanics say they use WD-40 on O-rings with no problems.
I don't think it's the same for silicone. But hay what do I know.
