You don't need to push the cap all the way down. You can push it about 3/4 of the way down and then pinch the top of the cap between your fingers and thumb and pull it back up. Then back down, then up, then down..etc.. while still pinching. Quick and easy. No lube needed.
(hope I didn't offend anyone)
Thanks for the clarification! This sounds a lot easier that what I have been doing. I guess I am a visual person and had my own interpretation!
