Since I've read the article of Chris Mrosko, I want to get the "Railweathering Solution" for my Friul tracks. But I can't find it anywhere. (must be very toxic).
Someone told me about a certain acid that attacks the white metal that I could get in the pharmacy. But I forgot its name.
There also was a thread about a product with the same effect. (not so good though)
Thanks for any help,
