This is a mini-kit that allows you to add Tank Treads to FOC Ruination Impactor; however these will also with Bruticus, Boosticus and many other toys thanks to the 5mm port. Lots of fun. The parts assemble for easy painting. I recommend getting WSF Unpolished white. Check overall fit and make minor adjustments with sandpaper as needed. Clean parts with dishwater and a soft brush (i.e. toothbrush) rinse thoroughly and allow to dry fully. Paint using very thin coats of Tamiya Acrylic paints directly onto the surface, no primer. Build up color to match. Thanks!
NOTE: I have also offered this in high-def Acrylate. Please consider this material in Beta as it is untested!
