Vallejo - Airbrush Flow Improver for Acrylic Paints 18 ml (0.60 fl.oz.)

Works for airbrush and regular bush equally well keeps the tip dry to a minimum using the airbrush also helps the paint level out nicely.

Came well packaged and performs as it should.

This is a must when I run my airbrush. A great product that helps keep things flowing! A must have for any miniature painter or airbrush enthusiast.

Works as described, but also, when using it as the “thinner” in acrylic paints, the finish is even better!

This stuff is great to help paint flow through my airbrush. Also makes it a little easier to clean when finished.

Vallejo Airbrush Flow Improver is one of those products that feels essential once you start using it—especially if you’re working with acrylics prone to drying in the airbrush nozzle. It definitely helps with smoother flow, reducing tip dry, and improving overall performance, particularly for fine detail work. However, it’s not a miracle cure. You still need to clean your airbrush regularly, and if you overdo it with the ratio, your paint can become too thin, leading to loss of opacity and potential spidering. It also slightly extends drying time, which can be helpful but sometimes annoying when working in layers. Overall, it’s a fantastic product that improves airbrush performance significantly, but it won’t completely eliminate the need for proper thinning, maintenance, and technique. A solid 4/5.

This is a good product, it has improved my airbrushes ability to paint longer with less time spent on getting it unclogged. Makes me smile about painting instead of dreading the endless stop and cleaning procedures I used to do.

It works! I like it combination with Army Painter Airbrush medium which seems like it has a bit of flow improver already in it. I like doing that with AK Paints especially through my 0.2 Creos. I use about 2:3:6 ratio; Two flow improver, three AP Airbrush medium, 6 AK. That's my standard anyway, your mileage may very considerably. Also works great with some more prone to dry inks like Vallejo game color inks.
