I disagree. The glycerine allows the paint to flow easier. Also, I never said anything about adding it to an airbrush! I also know how everything works, so stop being a troll!!! Your not educating, you’re dictating!!! Also, if I have got it wrong, which after extensive research I believe I haven’t, then please do correct me, please do tell me what goes in a flow aid!

I gotta agree here. Flow aid is a surfactant.

​​@@BudgetModelleri agree with him. I know you didn't specifically talk about airbrush, but acrylic isn't just reserved for using with a paint brush, and in spray guns it's crucial that it doesn't dry inside as it can gunk up the inside, which I have experienced first hand with spraying nails. Glycerines unique capability resides in being able to draw moisture from its surroundings, which is why it's often a key component in hand creams, even vaping devices and fog machines. You might seemingly reach a better flow with it as it lets the paint dry slower and makes it workable for longer without drying -and self leveling. Since flow aid is available in many countries that require chemical declaration of its composition, it's quite easy to tell you exactly what's in it: Oxirane, methyl-, polymer with oxirane, monophenyl ether and ar-styrenated - you could of course try and mix it all, but I don't recommend that 😅 -some of these ingredients are also found in dishwasher rinse aid, but I like mixing it with a drop of propylene glycol too. Try it out and feel the difference, it's very noticeable ❤ Xx

A flow aid would be dish soap dissolved in a bunch of water. Glycerin is not a flow aid, as it does not meaningfully change the surface tension of the paint, as it is not a surfactant.@@BudgetModeller

@@HappiSabi Hey! I just bought propylene glycol and I have some dishwasher rinse aid. In what proportions should I mix them with my thinner? (1/3 IPA, 2/3 water) Should I put some glycerin as well in the mix? Thanks!
