Extracted from the suffering sinuses of mature Mojave Macho male frogs in mating mode as fast as our wrugged wranglers can wround ‘em up off their free-wrange and herd ‘em in … just kidding!!
It is a sophisticated, specially secret formulated, room temperature curing, one-part "green" liquid plastic with very unique properties. BULLFROG SNOT was concocted and brewed by a veteran N-scaler specifically to be the ideal solution for improving traction on model railroads, but it can surely apply to numerous other quirky little problems left to be discovered by your creative fertile imagination.
Using a toothpick, apply one or two drops to a rotating driver (power the belly-up loco). BULLFROG SNOT forms a thin, very grippy plastic traction tire, virtually invisible after it cures. Apply just enough to evenly cover the surface with a thin coat. Too much makes a mess. Allow the wheels to continue to turn as you watch BULLFROG SNOT cure, let the laws of physics create a nice round tire, until the color is gone. Then let it fully cure overnight, or at least several hours. Don't rush it, let BULLFROG SNOT do it's thing. Patience has it's reward.
Most engines dramatically improve with one axle (two wheels) SNOT'd. Shelf queen steamers come to new life. Optimum placement and locations vary, so experiment! There is a 'sweet spot' that we must discover, and what doesn't work out is easily undone.
You get a perfect traction tire, or tires. Each application will be unique. Keep adding tires until the pick-up begins to suffer, then back off. Share your experiences. But, alas, there will just always be some engines BULLFROG SNOT can't help.
Why BULLFROG SNOT is ideal:

It is easily applied, and easily removed. Just a toothpick is all you'll need to install, an Xacto knife to remove.

It's ready to go - no multi-part mixing. No witches brew of acetone, RTV, buffalo glue, snake oil, belt dressing, two-sided tape, shrink tubing, chicken bones, eye of newt, or dilithium crystals

No disassembly, no special tools, no surgical skills

It cures at room temp in moments. No baking. No nasty fumes. It's benign and friendly

It’s easy to see your work, and it cures to virtually invisible.

It is thin – only .0055" or less when cured

It's tough and durable. Has a good service life

Leaves no residue on the track, and no gunk in your engine

Universal - works for any loco from any manufacturer

The above is the "official" company release on this product. We have been reading the various N Scale Forums with generally favorable reviews and also have had several of our "regulars" request this new product ... so here it is for those interested in experimenting. The potential is there ... the key appears to be in the "installation" -- i.e. even application. We welcome your feedback ...
