This item is used to slow the drying of acrylic paint. I have used it with Tamiya acrylics. Acrylic paint will dry very fast and open bottles of paint will skin over with drying paint before painting is completed and this product will reduce this tendency. It also aid airbrush cleaning as the paint will not dry inside the airbrush. A must have item. Only need a few drops at a time.

Great for hand painting figures. Put how ever much paint you need on to a wet pallet and put one to two drops of the paint retarder. This will allow your model to have a smooth finish after hand brushing

A short while back I tried this product. Now Tamiya is my go to acrylic paint. It, not only slows the drying time in the bottle but it also acts as a reducer to thin the paint also. If you haven't tried this product yet it's YOUR FAULT. Buy a bottle and amaze yourself....
