“and lastly it makes blending colors a breeze”
“you couldn't ask for a better price”
“Easy to use”
“Works real well”
“As advertised and on time”
“it did increase the realism for my drawing”
What buyers complain about
“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”
“24 hours later it is really drying slow”
“It was white not clear”
“Leaked”
“The bottle appears to have been opened, returned, or spilled”
