VallejoAirbrush Flow Improver for Acrylic Paints 200 ml. (6.76 fl.oz.)

First impression is it worked exactly as advertised. The one thing I hadn't realized is this is also a drying retarder so you need to keep that in mind as it takes a good long time to dry when used with my Vallejo primer.

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.

Great product

This product was a game changer for me. No more tip dry. This is amazing. Not a large vallejo selection in my small town

Another great Vallejo additive.Not much to say really, but this is a great way to minimize brush‐strokes.

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.

I’ve used a thinner in my airbrush for spraying base coats and zenithal highlights on minis and larger scale models for a couple of years and didn’t think this would make a difference. I was wrong. A few drops of this in the bucket with a couple of the thinner made even Army Painter matte white primer work well. That stuff is thick, dries fast and clogs the air brush pretty easy. No problems with this flow improver being added to the mix! Seriously changed how much I like using it to highlight.

One of my favorite thinning liquids! Price is decent for the volume and never fails to be useful for more than just thinning paints
