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

Yep - Blue pen.  Did it to 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

Thanks gents.

Ill shoot you a text let me know if you don't get it

I use Birchwood Casey PermaBlue Paste Blue.

 

If you're near Passaic Cty you are welcome to stop by and use it for free.

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.

Black sharpie for me.  Not sure how rust proof it is but I've never had any issues.

I have a marker for touching up ar's. I use that

Actually the same one pk posted
