Thanks for the info - I just realized I was wrong thinking the 6061-T6
came already anodized. I've been reading so many specifications I got
them mixed up.
I won't be anodizing....

Do NOT use steel wool on aluminum! It will leave tiny bits of steel
embedded in the surface and will induce electrolytic corrosion!

Why 6061? Most aircraft sheet metal is 2024 T-3 Alclad; structural is
2024 T-3 plate.
