Bullfrog snot

[Le Night ferry]

I'm trying to improve my old farish's locos.
To improve its traction, I'm trying to apply bullfrog snot.
Did someone use it?

DON'T DO IT.

If wheels are designed to have traction tyres they should have the correct type fitted. If they are not designed to have tyres  don't try to fit any, and definitely not any sort of substitute coating which will need you to apply an absolutely perfect even coating all around each wheel.

If you apply to all wheels the detrimental impact on electrical pickup will far outweigh any improvement in traction, and if you only apply to some wheels it will make them mismatched sizes which will potentially lift other wheels clear of the track reducing traction and increasing risk of derailment.

Not a product I would recommend at all.

If used on wheels not designed with grooves for tyres It will block the power pickup, and increase the diameter of the wheels which upsets the pickup of other close by wheels as well.

I wouldn't use it in the grooves of wheels designed for tyres either, unless totally unsuccessful trying to find the genuine tyres or 3rd party tyres which fit (there's usually some tyres which work).

I wonder why no one has come up with an electrically conducting version of this product.  Seems a logical development.
