It seems like you could have worked that into something, but if you ran right in for a kiss it might have been too much. She was probably just flirting, and my guess would be that diving in without restraint like a hungry dog wouldn't have gotten you far.
I would have twisted it a bit to make her want to demonstrate it to you. For example:
"blue jolly ranchers? you mean the lysol-flavored ones? that sounds terrible!"
"I guess you aren't as creepy as I thought-- and to think, all this time I've thought when you look at me and lick your lips that you just had a strange fetish for guys who look like Brad Pitt"
"I'm going to have to ask you to leave my car. chap stick is a gateway drug... next thing I know you'll be biting the [tie off my neck / shirt off me / etc.]"
Or just simply chuckle a little and say "not gonna work on me."
