### **What buyers complain about **

**Thickness**40%

*“Unlike other acrylic airbrush retarders that can be dispensed in droplet form this stuff is a thick, gooey gel which is impossible to measure accurately when creating the thinner mixture and that is critical because too much retarder and the paint both takes longer to dry and too little and the paint will start to dry in mid-air from the airbrush to the surface being painted”*
