What is Tundra?

Tundra is formulated with tungsten to provide the same density as lead, but at a lower cost than tungsten itself. Tundra is non-toxic, and can be easily cut, drilled or sanded to shape. You can substitute tundra for lead wire in any of our car plans.

How to Use this Product

Typically, 25/64 inch holes are drilled into the car body (see example below), and the tundra is glued into the holes - epoxy or hot glue adhesive is recommended. The tundra rods can be cut with wire cutters or with a fine-bladed saw. They can be also be drilled if needed.
