Travis,
Model Master Acryl paint is ready to airbrush straight from the bottle. There are two exceptions:
- The skin tone paints are thicker than the rest of the acryl paints. This is to aid in brush painting.
- For fine line work, thinning may be required.
The best thinner is Model Master Acryl Thinner. I would also suggest getting Model Master Acryl Cleaner for cleaning brushes and airbrushes. The cleaner is a little more aggresive than the thinner. Also good to get is Model Master Dried Acryl Cleaner.
For thinning for fine line work, only put a drop or two of thinner into the paint at a time. A little goes a long way. First try airbrushing with out thinning. I've never had to thin my Acryl paints and I've been using them for years.
This model was painted all with Acryl:
I did the camo free-hand and didn't have to thin the paint.
