The instructions called for XF-63 German Grey and XF-54 Dark Sea Grey, but I decided to go with black and Neutral Grey (XF-53) as it what I had on hand. I like how it came out.
Long story short... the original bonnet was cracked while trying to sand the line away. Bought a replacement and it had the same thing. Used 4000 grit sanding pad and the three Tamiya compounds and it came up good.
Forgot the progress shots, but this is the finished bonnet with SMS Blackcurrant over SMS Jet Black. Thr clear coat on the underside is SMS Super Clear.
