Scratch on buffer tube?

[The Soup Nazi]

Well, finally got the complete lower today, everything seems fine, though I do want to fix up some of the scratching on the buffer tube. These are pretty large obvious ones, athough the only cover a fraction of the tube, is this where you use a sharpie/paint? Or is this another problem solvable with CLP?

It's aluminum. You can use Birchwood Casey Alumi Black to chemically blacken the bare metal.

You can find it at Reed's or most any gunshop. I've even seen it at Wal-Mart.

Why would you want to touch-up the buffer tube?

Put a stock on it.
