I was very interested in what you were asking because I paint with other
products beside car paint and most of them have no thinning instructions
for spraying. Like wood polyurethane, meant to be put on with a brush
but some spray it so how much do you thin?
everyone I've asked gives me a different answer.
Somewhere, someplace there's bound to be a chart or something
stateing what viscosity matches what tip size.
I would love to see that.
