Hi everyone!
I luvs me my air brush! But I was wondering if I could use something other than Testers air brush thinner when I’m thinning my Tester’s enamels. The Testers container is rather pricey. Anyone have any advice? Thanks!

Absolutely! Mineral spirits paint thinners can be used with outstanding results. They’re available at any hardware store for just a couple bucks for a quart can. Since they contain petroleum distillates, the residue they leave behind also provides a little lubrication for your airbrush.

Lacquer thinner
I wonder if this is all Model Master thinner is? It sure smells similar doesn’t it? [:D]

Yep, I started using lacquer thinner about a year ago and everything just started to work a whole lot better. I also use Dupont enamel reducer.

I’m going to have to try that Murray.
I would think the lacquer thinner would also be a big help in breaking down any paint particles that were trying to clump and aid in spraying.

For years I’ve used Dupont Enamel Reducer 3812s - got a gallon under my bench as I type this - Works well with Humbrol too - Cost just went up though, my last gallon cost me $17.95 - Beats the cost of buying the same amount of Model Master thinner (2 oz @ $2.49 vs 128 oz @ $17.95) - think it can be bought in quarts too.
I use T.R.P.S.(Turpentine Replacement Solvent) for Model Master and other enamels. It is very inexpensive around $2.00 for 1US Quart in my area, thins enamel better (IMHO) than MM thinner…must be something in the ingredients. It is very low oder, and works effectively well for cleaning the airbrush as well. If you can find this in your area, give it a try!
Oh my gosh! Thanks guys! I’ve got a quart of mineral spirits down in my basement already! Little did I know that I could have been using it all this time as an airbrush thinner. I knew it was good for cleaning brushes and such but I didn’t know you could thin your paints down with it too. This just made my day!
