Tru-Color's 3-D formula paints are intended to be used with fragile 3-D printing models. The paint is designed to adhere better than the sprayable line. Some modelers using the regular spray formula will use Tru-Color's Primer and achieve the intended results.
Tru-Color Paint is an Acrylic 'hot' paint formula with a combination of Acetone and other media for its base. Ventilation when using this paint is required.
