Description
Fill-It is a sulfur free clay used by mold makers to seal mold boxes, build dams, set parting lines/shims and repair cracks. It is off white with excellent adhesive and feathering characteristics. It is also very flexible and will not dry or crack.
Fill-It is soft and easier to handle at lower temperatures. The smallest amount of heat, just friction from rubbing it in your hands, will soften the product.
Fill-It is packaged as one pound blocks, which are scored so that they can be broken into quarter pound sticks.
