I have been using the MTH grease in my engines. I'm just about out and its time to resupply. Should I stick with the MTH stuff or are there better products out there? What do you use?
EDIT: Wow! Thanks for all of the replies. Looks like the Red & Tacky comes in first by a landslide, followed by the Labelle. And a surprise third place to Mobil. I never thought about using automotive products on my trains. I think I will be trying the Red & Tacky.
