Thanks for all the replies
I should have made myself more clear but most of you have worked it out.I was thinking specifically about blending colours without the use of stencils and masking tape etc, although I do use those for the details. Also spraying the backs of narrow lures was always a problem so thanks to Mark for the tip on that. I will have a look at the different nozzles as well and see what I come up with. Thanks again guys.
Doomdart, my avatar is a fish I caught on a recent trip to India. It has been a lifelong ambition to catch one of these so I'm very happy. Doesn't look that big in the picture but it's a 55lb Silver Mahseer, reputed to be the hardest fighting freshwater fish in the world. I've changed the colour of the photo though to make it look a bit 'olde worlde'.
