I wish the foil was darker and more closely replicated stainless steel but I have a bunch of aluminum on hand and I'm also afraid that if I stopped a week to wait for foil then I'd lose my momentum and not finish the model again. I'll darken it up when I start weathering and they won't be so bright.
It was interesting to me when I started paying close attention to exactly where the stainless starts and stops, that almost every operator has painted their panels differently. On the engine cowls, some such as 909 have just the small section that I applied the foil too, and some of them are unpainted to the next joint back. On exhaust areas some are unpainted on engines 2 and 3 where it leaves the cowl around the landing gear, some are painted. On the undersides around the turbos everybody seems to have done something different there too. Even during different periods in it's life 909 sometimes did or did not have paint around the exhausts on the 2 and 3 nacelles. I
think what I've done correctly depicts 909 for the time period I'm trying to replicate.
I have some minor paint touch up to do and then I think I'm reading for decals tomorrow.
