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

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.

works well
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.

It works.
It does what it was formulated to do adequately. I have zero complaints, but since the seller is demanding my review, here you go. It works.

Good for thinning airbrush paint
I paint lures and run across paints that need to be thinned a lot. This definitely does that well and does not effect the color at all. I usually use a few drops and mix to see if the consistency is what I'm looking for. Definitely a great buy and worth having in your arsenal.

Makes paint texture odd sometimes
For some reason this thinner produces inconsistent results with nearly identical ratios - not enough for me to call this a bad product. But for applications like mini painting, I've had some hiccups.

Easy to use
I like this product to use with my air brush gun the amount you use depends on the type of paint you use. It’s very thick so keep on checking your paint on how watery you want it. Its good price as well
