Tamiya acrylics sometimes kinda suck for brushing, because you need to work fast and need to be careful of painting over anything. This stuff gives you a little more time to get the depth of color you want with a brush.
A necessary addition for airbrushing. The product slows the drying time of the paint which helps when spraying. TPR will help keep the paint from drying from the brush to the surface. Just a few drops are all it takes.
"Paint retarder a must have."
moutons (western NC)
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.
"Excellent for figure painting"
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
