my new and LAST question is how to apply the lubricant. when should i apply it? should i apply it before breaking a cube in? please include these and many more details. including when. thanks guys!
Just a suggestion, you might want to try to include all your questions in the first post. I found that to help more than asking different stuff over and over again.
The lube Rubik's.com sells is
identical to PuzzleProz lube. That lube is decent, but I never liked those because they are too "watery" in my opinion. If you are sloppy, then chances are you are going to get that lube all over your hands and outside of your cube as well, making it difficult to cube because the surface has been lubed too.
The syringe for those aren't that great either. If you press a bit too hard, then too much lube comes out and makes your cube all sticky and greasy. If you don't mind all this, then I'd say go with the PuzzleProz lube (because puzzleproz sells it at a cheaper price than Rubik's.com)
Anyway, I recommend using CRC silicone spray or shock oil weight 20. For the spray or shock oil, I recommend taking out an edge and then spraying/oiling. If you use spray, I'd say spray for no more than 2 seconds. Why? Because if you use too much spray, then your cube will become super sticky. If you use shock oil, be careful to use only one or two drops. If you use too much, your cube will become sticky too.
I found it best for my cubes to be broken in prior to lubing. What the lube does is it coats the inner surface with the lube. If you try to break in the cube after you lube, you are NOT breaking in the cube -- you are breaking in that coating of lube. So when the lube wears out (which it eventually will) you will have to go through the process all over again, which you don't have to go through multiple times if you break in the cube before you lube in the first place.
Just another thing -- mixing shock oil weight 80 and PuzzleProz lubes and then lubing with that mixture supposedly works too (keep in mind that I heard this somewhere else in this forum, I never actually tried this)
