Actually there is a pile in the archives but I've never seen and never really tried alternative CP materials. The consensus (with which I so far concur) is that nothing works. Clearly the best solution is to change the parts but I'm open to other options if it turns out there are any.

Anyway - simply replacing the verdigris-infested parts has been the option of choice for well over three decades. For a long time, the problem with doing so was that the factory parts were so variable in quality and dimension that they weren't necessarily an improvement and most of us who have been doing this for a while simply had to use other parts that worked...sort of. While it definitely wasn't optimum in any sense, that solution bypassed all of the perniciously repetitious problems that went along with trying to rework the older parts. This is one area in which I think that we are incredibly fortunate today that there are so many alternatives for dealing with so many of the problems that used to be major problems for rebuilders. There is almost an embarrassment of riches in terms of quality parts, hammers, and strings out there; to say nothing of very high quality boards and blocks. It's a double-bind, in a way, because it raises to new importance questions around whether or not we really are artisans and technicians or simply new parts installers. Best.
