3-D Colors
This new formula paint is made for 3-D printed, and resin cast models. In order to adhere better to these items that normal model paint has difficulty adhering to, this formula has been developed with additional adhesion promoters.
To adhere better, this paint dries SLOWER than Tru-Color Paint's other formulas. This allows the paint to get a better 'bite' on the model. The question has been asked, "Why not do this formula for all colors?". The answer is most modelers not painting items like these will not be happy with the slow drying of the paint.
Another question is "Why not use your primer and then the standard formula to paint these types of models?" This answer is the less these items are handled, the better. Masking and more handling will lead to damage of the fragile 3-D models.
