Bullfrog Snot, Liquid Plastic Traction Tire 1oz (BFS1)

Bullfrog Snot is a liquid traction enhancer for model locomotives, designed to improve grip on traction tires and help engines pull longer trains or tackle grades with ease. Packaged in a 1 oz jar, it’s easy to apply with just a toothpick, requires no mixing, and cures at room temperature in moments, leaving a nearly invisible, ultra-thin film on the tires.

Its universal formula works with locomotives from any manufacturer and in any scale. Once cured, the coating forms a very thin layer—about 0.0055 inches or less—that won’t interfere with clearances or operation. It leaves no residue on the track and no gunk in the engine, can be thinned with plain water if desired, and requires no disassembly or special tools, making it a straightforward upgrade for hobbyists seeking improved traction.
