Review: Excellent! Ample, effective & economical - Item is ideal. Price is More than reasonable. Thinning the paint properly is a "talent" in itself. It's your first step towards your project outcome being"trash or treasure". Not to mention protecting & maintaining your Airbrush. Yes, you could use distilled water but for the time & money already invested. It's definitely $10 well spent. 5 ⭐'z from me
Review: works great - The bottle is bigger than it seems on pictures and this bottle will last me a while. It thins great but it takes a little practice to get a good consistency. Overall I would say this is a genuinely good product, it is simple and has practically no downsides.

The bottle is bigger than it seems on pictures and this bottle will last me a while. It thins great but it takes a little practice to get a good consistency. Overall I would say this is a genuinely good product, it is simple and has practically no downsides.

### ⭐⭐⭐⭐ works well
*by S***H on August 11, 2025*

Works great for what its for. It dries how it says its supposed to. I use a lot of the Turbo Dork airbrush paints and they have a lot of pigment and sparkle so this is a must to use them without things getting clogged up. It doesn't change the color or anything. It makes the consistency way easier to work with. There's actually a lot of product for the price.
