Thanks Cook,
The best way to paint I find is painting in batches 5 or 10 minis at a time a colour at a time .
As I said before ,having undercoat & base coat beforehand ( sometimes even months before ) helps a lot.
That does not mean that I'm always painting, sometimes I just look at the minis for a month or so.
Something like that , I have loads of wheels from broken cars etc,
