Touching up black aluminum

[Racer X]

I was wondering about the BWC marker. I think my plan is the Sharpie Industrial after wiping the areas down with IPA. Then if that doesn't work, the BWC Aluminum marker pen. The Sharpie I can get easily tomorrow. THe BWC pen should be at my local fun store.

Worst case is this handy little bugger from Krylon, a SEMI gloss black paint pen. Not flat, not gloss. Gotta find a single one in town. Everywhere will order a six pack only. 215123
