Bullfrog Snot

Bullfrog Snot is the hobbyist's secret weapon for improving locomotive traction on model railroads. This unique liquid compound is applied to drive wheels to create a grippy, rubber-like coating that dramatically improves pulling power on grades and curves. Compatible with HO, N, O, and other scales, Bullfrog Snot is a simple, affordable upgrade that makes a noticeable difference — especially for heavy freight consists or challenging layouts.
