Krusty, you very well could be right. The more I look at those specific areas the more it looks bare metal. This is a great thing if true! I was wanting more metal showing on her and even though I was first drawn thinking it was white..bare metal rocks with OD!
Im also tinkering with a new technique to add more heat damage to the paint from the engines (very worn with a burned effect, making the paint covering much thinner in areas.)
Anyway, I will look more for the specific answer to the color. However, I think you are correct.
