Micro Slick is manufactured by NIC (makers of cerakote). It's a dry film lubricant that is thinner than cerakote. It isn't as corrosion resistant as cerakote, but according to the folks at NIC, it provides about 1/2 the corrosion protection that cerakote does (which is still more than most other coatings).
I have used it on bolt bodies and the bolt carrier groups on AR's. It's a slick coating and gray in color. Just about a perfect match to Cerakote Sniper Grey.
