Traction tires or bullfrog snot?

[RobertInOntario]

My caulking solution is working reasonably well, although the wheels are a little gooey with some grunge building up. I'm viewing this as a short-term solution thinking that the bullfrog snot will be a much better option. Seems like it's easier and cleaner to apply (ie less messy).

Yes, you only apply it (either the caulking or bullfrog snot) to one wheel set and that's enough to give the loco more pulling power. The other wheels will do the electrical pickup.

My loco is wobbling a little and not as smooth as it used to be, again because the caulking is messy and uneven.
