You could always BMF them, I think it would be less frustrating than trying to pick them out with a hard leaded pencil. A softer HB pencil might work a little better but I'd still think about the foil option.
Hoping not to re-create the fiasco from my last forum foray. Anyway the name's Bill I've been building for longer than I care to remember but still enjoy my time at the bench. Looking forward to interacting with fellow modelers.
