Hi Alan,

1 to 1 mix with latex is too thin. It will probably run when you spray it. With a touchup gun I start with maybe 15 to 20 % water. It depends on the color, too. The lighter colors seem to have a heavier pigment and need to be thinned more, but you have to experiment. Even with the airbrush I thin it maybe 25% and go from there.

I keep a hairdryer handy for speeding up drying between coats and also to dry it fast if a run starts to happen. Vaillancourt's article recommends a heatgun but I think that's too hot. A hairdryer works fine. I also like to have a detergent solution and a small, stiff brush handy for cleaning off the needle if the paint builds up on it.

Lot's of luck with your painting![sm=thumbup.gif]
