The Rocket is a fine little APV but dumping juice inside will be an ongoing problem with potentially disastrous end results unless owners find a way of sealing the top from leaky Vaporizer. My idea, post #1843 solved the problem for me though esthetically it may not be a solution for most.
Kellymcm's method with Nail Polish, post #1844 might be a better solution for some, probably requiring two or three coats. With a little imagination it could end up being decorative.
Whatever solution owners come up with I strongly suggest a plugged shorty 510 extension, it will make whatever solution you come up with a lot easier. If you don't have a sealed 510 extension just plug the hole with a toothpick to keep juice from seeping through the vent hole.
