Thank you,

i use alcohol

do you thin acrylics with alcohol for airbrushing or for filling in recesses by hand?? thanks bill

Here is a solution throw the acrylics out the window and buy enamel.

I use their acrylic thinner. Costs more but no suprises to ruin a
finish. I’m going to try Huskerguys suggestion also.
