A question to the Airbrush kings we have on here, what is the difference between Airbrush Flow Improver and Airbrush Thinners and what are their uses?

Thinner does what it says, it thins the paint.

flow improver is an additive that helps to break surface tension, allowing paint to be applied more smoothly.
if you have a paint that comes out streaky with a brush, or an uneven coat with an airbrush you can resolve it with flow improver. It also acts as a retarder, and also because it breaks surface tension it also acts in small quantities as a lubricant for the paint in an airbrush so it can come out easier, and be cleaned easier.

@killcrazy I think that there might also be a drying additive (isopropyl alcohol) to the thinner. Luke’s APS did a video on how to make your own and added it to his. It seems to be common in other videos as well. I found that thinner was best for priming to cut the cure time down a little whereas the flow aid was best for regular air work to get the most time to clear out any gunk in the system. Humidity really is a factor to consider when using an airbrush.

Flow Improver is also supposed to help prevent the paint drying on the needle tip.
