I spent quite a while masking up the white - I used
Tamiya masking sheet, sadly the masking tape I had was 10mm wide - the stripes are 12.5mm & rather than overlapping tape, I had to cut the correct width from plain sheet.

I used Hataka Night Black ( it was the first black I came across in my paintbox )

After a couple of hours drying time ( OK, I was at the pub! ), I sprayed the underside Vallejo Sky Type 'S'.

I'll let this dry overnight, and see if it needs another coat. If not, then I'll mask up the Sky demarcation line and hit the top with Dark Sea Grey
