I never understood the point of CA kicker. By the time I can grab the bottle of kicker, move it into place and start spraying, the CA is almost set anyhow... and since I wasn't using both hands to hold the part, it's set at a crooked angle.
I suggest that if you are the least bit worried about the kicker affecting the plastic, it's not worth it for the few seconds you'll save. Or, follow the old addage from the textiles industry, "test product first on a sample or unseen area."
Now, if someone came out with a kicker for epoxy, so that I'd have lots of working time but then be able to set it nearly instantly once I'm done, I'd be a happy man.
