Neolube - does it work well? (pic)

Anyone tried that Neolube #2 that I see in the Micromark catalogue? I want to tone down the connecting rods on my Heisler (see picture) and the shafts on my Roundhouse Shays. What happens if it get on plastic? Pro-cons?

Thanks …

I posted the same question a few weeks ago, and the response was quite positive. Here’s the link: Any experience with Micro-Mark’s Neolube or Zamac plating kit?

Very nice pic, btw.
