Comments: The name may make it sound like a joke, but it’s Snot.
Bullfrog Snot is a one-part, self-curing liquid plastic designed to be applied to the tread of model locomotive wheels. When it dries 24 hours after application, it forms a thin, greenish traction tire.
I used a scrap of stripwood to apply Bullfrog Snot to one set of wheels on two locomotives, an Atlas HO scale Fairbanks-Morse H-16-44 and a Life-Like N scale RS-2. The results were significant.
According to the force meter in our workshop, which we use to measure drawbar pull, the N scale Alco went from having a drawbar pull of .64 ounces (equivalent to 15 cars on straight and level track) to .96 ounces (equal to 23 cars). The HO scale road switcher went from a drawbar pull of 3.52 ounces (49 cars) to 8.8 ounces (123 cars).
Bullfrog Snot is a boon for locomotive models with poor traction.
