80% milled..protect the inside?

[Sillyguy]

hey all

i got one of my 80%'s milled. the out side was already anodized black. the inside is all raw aluminum.

do i need to paint/protect the inside? If so, what do you guys recommend?

Thanks.

You dont have to. But there are plenty of options out there.

I have a couple lowers two years old with nothing on them, they are fine!

[gesundheit]

You are good to go. No need to do much on the insides.

[Sillyguy]

ah ok. thanks so much guys!

nope. you can if you want, but it isn't required

If someone was to coat the inside, what would you guys recommend? Alumahyde?

[jfifer]

Rattle can. Bake it at 300 for one hour. Cool down. Repeat 3 times. Then try and scratch it off. Cause you cant.

If you wanted to, you can use a chromate conversion coating, commercially known as alodine to the inside pocket.
It also promotes improved adhesion for coatings

I think raw Aluminum will quickly form a coating of Aluminum Oxide that is a hard layer you may not be able to see. Unless you get something corrosive in there, I doubt you would ever have an issue.
