Tamiya X-20A is the dedicated thinning and clean-up liquid for Tamiya Color Acrylic paints. Use it when adjusting paint before application, then again at the bench-cleaning stage to wipe away paint residue and wash brushes. Its stated compatibility is specific to Tamiya's acrylic colour range, so it should be selected for that paint system rather than treated as a general-purpose thinner.
Formulated for use with Tamiya Color Acrylic paints.
Dilutes paint before brush or airbrush application.
Can be used to wipe away acrylic paint residue.
Suitable for washing brushes and cleaning painting tools.

Notes · Q & A
What's the difference between a paint and a wash?+
Paints are opaque colour for coverage; washes are thin, pigmented fluids that flow into recesses to add shading and depth. Most painters use both.
Can I use these paints in an airbrush?+
Many acrylics can be thinned for airbrushing — check the product description; ranges marked "Air" or "airbrush-ready" work straight from the bottle.
Do I need a primer?+
Yes for bare plastic, resin or metal — primer gives paint a surface to grip and prevents chipping.
