RE: What is best 'House Paint' to use? And, anything special used for Airbrush thinning?
I've got that book Richard mentioned and have gone to Home Depot and Lowes. This works great, just remember to tell them not to get ANY paint on the book. The guy wanted to brush a dab on the color chip to make sure it matched. I went ballistic and he quickly pulled back. Too expensive and valuable to have someone do that to it. I highly recommend getting one, well worth it.
