when i toked on mostly j's, sometimes i'd get a glob of goo from the end but can't recall it ever being a long term prob (embarrassing at times tho)...i burn bowls now and as long as the pipe stays clean no resin drips out...unless it gets left sitting in the direct sun. then it's a fuckin mess! anyway, back to cleaning lips...toothpaste rubbed into a wet washcloth will take it off...along with more alcohol-soaked washcloths.
