Cerakote Finishing
The new kid on the block. And I ain't talking about that horrid 90's boy band. Lets just start by saying Cerakoting is a great finish! Now it's not for everybody, and certainly does not belong on an antique restoration (my opinion), but you just can't beat the durability and corrosion resistance of this finish.
Cerakote has the advantage of being any color you'd like it in, and there are some who can do some amazing artwork with this stuff.
This is a very fitting finish for new firearms and many custom guns as well. This finish also pairs really well with the older finishes when executed correctly.
