+1 to silicon grease on the inside
But I recommend synthetic grease on the outside of the cylinder, moly grease tends to attract dirt and cake up, it also gets pretty stiff in cold weather (we use lots of it at work)
I've never had any issues in 3 years of using synthetic grease on all my guns through hot and cold weather.
Tamiya connectors suck.
