X-20A Acrylic Thinner 250ml Bottle (TAM81040)

X-20A Acrylic Paint Thinner is a 250ml bottle designed to thin Tamiya acrylic paints for smooth, even coverage in both brush and spray applications. It supports the performance of water-based acrylic colors, helping paints flow smoothly, blend easily, and maintain a consistent finish when thinning as part of an acrylic painting system.

Designed for use with a variety of modeling materials—including styrene resins, styrofoam, wood, and common plastics—this thinner enables versatile prep for painting projects. A stir stick is recommended to mix thoroughly before use, helping ensure the right consistency for reliable thinning and a professional-looking finish.
