thinning enamel

Can you use 100% mineral spirits to thin enamel paint for airbrushing?

The answer is probably yes. Technically it seems should work, but one must be aware that any given paint product may react unpredictably with other compounds used in model finishing. In my younger days with my first airbrush I could only find Testors thinner in the little bottles, which became costly to use since I was buying it with lawn mowing money, so I experimented with less costly paint thinners that Dad had in the basement. Many of these experiments did not work, though I have long since forgotten the specific products I used.

Clearly, if you are experimenting with thinners, try it on a scrap body first. And remember, bad reactions with other products (paints, primers, fillers, plastic, etc) can occur. The thinner used may also require altering your air brushing technique.

Personally, I would recommend sticking with the thinners made for the paint you are using, or use cheap hardware store lacquer thinners. Many builders, myself included, are using lacquer thinners for thinning hobby lacquers and enamels with good result. However, I encourage experimentation, so if you try it, let us know how it works.

I would recommend using lacquer thinner.  Thin your paint to the consistancy of milk with the thinner and then spray it on a scrap body to check if it will work for you.  The best thing for you is to experiment a bit with mixtures to see what works best for you.  Once you find that level, stick with it.
