Hi.
This is something I came up with some 10-12 years ago and had posted it in another MRR forum.
I have no proof others haven't done this before. But it is my sworn testimony under penalty of perjury I never saw/read about it elsewhere.
So, it could be an original..I like to think so, anyway..
~ Get a tiny bottle of Chrome enamel paint (same as nail polish I believe), and paint the 4 insulators around your Atlas or Peco TO frogs and crossing frogs, and any other black/brown plastic rail insulators lurkin' about..It's a nice visual addition and is why I put it in this category.
When I had it on my last layout, nothing seemed to wear it away, such as brite boy, alcohol, burnishing, or wheels. And if it ever did you just re-do...
If you fear it will lift drivers you can take down the plastic a smidge, first. But it must be somewhere near 128th" !...
Hope you like it. I've 2 more I also may be first with..But that's for anoth......M
