Another Badger 155 Q?

Yes it's true. If you are spraying enamels, you can use Model Master airbrush thinner. It's worked for me in the past because it makes the paint flow and lay down very nicely. I use acrylics pretty exclusively now and I am still experimenting with thinner ratios for those.

Is it true then that if I am using paint that is not normally used for airbrushing such as some Model Masters, or the little bottles of Testors, that I should add thinner until it has the consistency of milk, hey I really appreciate this advice, truly invaluable.

oh yeah - you'll probably find using the metal color cup is the way to go for most painting... only large coverage gets the bottle for me.. it just sprays better and is easier to clean up using the paint cup... in fact if you can get hold of another one it makes it REAL easy!!! take the one with paint off, put thinner in it... take the other one put thinner in it and clean the brush... then you can wipe out the paint with a qtip and wipe it down with a paper towel on the one used for paint...

Cryptic - better than those for cleaning the 155 is lacquer thinner or mineral spirits... you can get them at the hardware store for about $4 a quart. If you don't feel safe spraying these regular thinner works..

here's a good link to cleaning an airbrush, it helps if you have more than one paint cup or bottle to do it quick...

as far as how long I'll let paint sit in my airbrush before cleaning it out I would give it about 15 minutes for enamel maybe 10 for acrylics before deciding to clean it. sometimes I will put some of that glad press and seal over the color cup between spraying to help keep it from drying, before spraying I will let a good shot of it out onto a paper towel to clear andy thick paint out for spraying...
