I recently discovered this,
, while working on my gun late at night. I thought the cure was more silicone in it's vital spots, but I was sadly mistaken. The more lube the more clogged and oily the gun is. The cure is exactly the opposite. Less lube on the gun helps it to perform better. In the Mac's case, a little lube goes a long way. Next time your cleaning your Mac, think about this and give it a try.
