When perfection is your goal, the Tamiya Basic Type Putty is your go-to for seam-filling finesse. Ideal for plastic model kits and RC models crafted from ABS or styrene, this gray putty takes your assembly game up a notch. Simply apply it with a flat surface tool to smooth out seams and imperfections. Just a heads-up, this isn't gap filler; it's more like the finishing touch for models striving for flawlessness. Also compatible with resin, metal, and vinyl models, because we like to keep your options open!
