To be fair I never said that it was inferior product. I voiced a concern about its viscosity with respect to plastic cased 2-rail gearboxes “The excess heat could weaken or warp the plastic. This is an educated guess from someone with a degree in chemistry. I may be wrong or I may be right.”
i also OPINED that RNT would be OK for all metal gearboxes, (Weaver, MTH, ETC ) but that’s opinion. I may be wrong. Time will tell.
i have to say this topic is worn out IMO.
Huh? you said (and this is a direct quote) "The lubricity of Tacky may be inadequate for the plastics or even damage them" in response to one of my posts. As explained previously, I use red and tacky on a number of hard run engines with plastic gears. As such, this is of great concern to me. The word "inferior" is a synonym for "inadequate". So not to quibble but that sentence is definitely calling the grease possibly inferior for its use on plastic gears and any reasonable reader would interpret it as such. To be fair, if you didn't mean to say it, then you may want to edit your post on the first page.
But hey, we totally agree on one thing - this topic is worn out. I'll leave this thread since there are no facts to support your claim nor has anyone observed plastic gear warpage in connection with RNT over the decades of its use by model train hobbyists.
