Andrew, I don't know how I do it other than I've done brush painting for over 45 years. I try not to put too much paint on the brush and I buy good brushes. I mask off things too, this wasn't done free hand. Well not all of it anyways.
The paints were all Model Master paints on this one. I prefer Humbrol but the Hobby Shops in my area no longer stock it. I have ordered some on line before though.
I'm at work now, so I'll post the actual colors I used later if you want.
Glad people have enjoyed the SPAD, I tend to over criticize myself.
