Adding additional support, particularly in relation to Fowlers Fury posts, as a ‘One-Clock-Expert’ I deliberately let rip with a spray can of stuff not only on my ‘one and only’ (unfinished) timepiece but that of the mechanism of a commercial longcase clock belonging to a late friend. It had stopped working so it obviously needed spraying according to the many claims of said stuff.
That was at least thirty years ago long before I knew better.
Stepping back even further … well you can read the paragraph for yourselves taken from a seven part article I wrote for Model Engineer…………
Building John Stevens’ Skeleton Clock – Part 1 – #4526 – 22 Jan 2016
By about 1976, and because of a couple of technical setbacks, none the least being the balance spring, I shelved the project, literally. There it stood slowly gathering dust, rust, and some sort of hard, brown tarnish. A liberal dose of a well-known water-repellent spray seemed to have helped in developing this hard coating. It covered every piece of brass. Protection of the steel parts (especially the arbours) was also lacking. These latter issues only became obvious years later, when I was eventually encouraged to finish the clock and began to pull it apart.
When I finally finished the clock, I received a gift from an extremely generous clockmaker.
About 2ml each of three grades of clock oil. Enough to last centuries. So maybe you can find someone similarly generous?
