How much paint do I need for a 1:48 aircraft?

A typical 1:48 aircraft needs about 3-5ml of paint per colour if airbrushed with 2 coats. With 5-6 colours, expect to use 15-25ml of paint total plus thinner. One 17ml pot of each colour is usually enough.

Does airbrushing use more or less paint than brushing?

Airbrushing uses less paint per coat than brushing because it applies thinner, more even layers. However, you need thinner as well (typically 1:1 to 2:1 thinner to paint), which increases total liquid volume. Overall, airbrushing is more efficient with paint.

How much primer do I need?

Primer covers the entire model surface. For a 1:48 aircraft, expect to use about 2-3ml of spray primer. A single 180ml rattle can of primer is enough for many models.

Should I thin paint for brushing?

Yes, slightly thinned paint flows better and avoids visible brush strokes. Add about 10-30% thinner for brush painting. Thin enough that the paint flows smoothly but still covers in 2-3 coats.
