My dad was generous enough to bring back Mothers Mag & Aluminium Polish from the US.
Before, I was polishing (or attempting) with a 26-year old can of Brasso, but didn’t seem to work too well.
This stuff (not the old Brass) is amazing!
Here’s my hand polished UltraFire C3 SS and CQG S2:
I was conveniently able to polish the S2 by putting it inside a drill and rotating it, but the C3 didn’t fit and I couldn’t get a complete mirror finish.
