Well I finished High School Chemistry 50 years ago now but my recollection is that iron or steel plated with tin won't rust. However, if the tin is scrapped off the iron it will rust worse than if it had not been plated because of the ion left there. Scrape some tin from a tin can and see how quickly it rusts. Zink on the other hand protects the iron even after it's been scrapped off, again because of the effect of the ion left. Can't use that with cans for food though as the Zink would contaminate the food. Yes, that is 50 year old chemistry but I think those elements still have pretty much the same properties! dp ____________________ David M.

I just looked up their catalogue, on line, and they have a Roslau Red, that is plated. http://www.fletcher-newman.co.uk/catalogue/piano_wire_strings/index.html It doesn't mention the tropics, and that is where I thought I got the idea, in their old catalogue. If not to resist rust, why have the plated wire? John M.

Ross Windsor, Nova Scotia, Canada If there are "tropicalized" rust resistant wire out there, they haven't shown up in any of the pianos in Hawaii. Most of the ones I am tuning have rusty strings, some worse than others.
