Tru Color Paints are the modelers choice! I use them and recommend them! Tru-Color Paint is a solvent based paint with an acrylic polymer used as the binding agent which adheres very well to plastic or metal models, when those models are properly prepared. The pigments and/or dyes used to produce the correct colors are very finely ground so that they do not clog air-brushes. To insure proper adhesion for plastic models - wash the model in mild soapy water to remove residual processing oils and dirt, rinse thoroughly with clean water and let dry or use a lint free cloth to dry. It is now ready to be painted. For metal models (brass for example), sand blast or treat the metal surface in some fashion to give Tru-Color Paint a prepared surface to adhere to. Then use our Primer, Tru-Color Paint 07, and spray paint the model, allow sufficient drying time and then paint the model with the desired color(s).
