I will only use this method for a compete refill, a new blank or freshly cleaned cartomizer. Fifteen drops in the condom and slowly slide the mouth end down, then spin and repeat with another fifteen drops and give it a short final spin.
It wasn't messy at all for me, wiped the cartomizer and inside of the condom and done.
