Dremeled off bayo lug, best method to rust-proof bare metal?

[DirtyDigz 1,812]

I dremeled off a bayo lug on a new upper I bought - what's the best method to coat the bare metal I exposed so it doesn't rust?

Get one of the blueing touch up pens. If you want to come by my garden center you can borrow mine

Thanks gents.

 

Loslow, PM your garden center location.

The blue pen won't rust proof the metal --  It'll just change the color to almost match 

 

Use some sort of rust preventative after coloring, just like any other steel part of the gun

 

I'm really liking eezox as a protectant on the outer metal surfaces -- sucks as a lube but really does prevent rust

I use a bluing pen and then oil.  Works and matches pretty well

 

You're local I think and can do it if you like.

You're not local unless I'm on my way up to Cherry Ridge, but damn I at least owe you a visit and a 6 pack of your favorite beverage for all the times you've offered to help me with various stuff.

No brew!   Just hook-up  degrease, blue and oil.
