Air Bubbles in Tamiya Paint Using Battery-Operated Badger Mixer

After you mix the paint stick the paint bottle in a vacuum chamber and the air bubbles will disapear.

Just kidding of course.

Most of those bubbles will disappear after you reduce it with thinner.

And there is no way to get an intact air bubble through a properly working airbrush, which is atomizing the paint in a stream of air. If any bubbles appear in the paint on the model, you are laying it on too thick and too cold.

This is completely normal for any powered mixing of any paint. There are only two downsides, both relatively minor:

1. If you measure the amount of paint that you intend to reduce for spraying, and measure the amount of reducing solvent that you use, you will have slightly less paint than your measurement because of the air volume.
2. Air (oxygen in particular) is the enemy of all uncured coatings. This is not usually a problem unless you regularly froth your paints and plan on keeping them for years.
