Tamiya Basic Type Putty is used for filling in seams when assembling plastic model kits or RC models that use ABS or styrene plastic bodies. The putty is gray in color and may be applied with a flat surface tool. 
Note: Tamiya's basic type putty is not intended to fill large gaps. It is meant to fill in seams and imperfections in plastic model surfaces. The basic putty may also be used for resin model, metal model and vinyl model applications.
