SWIM figured that SS and HgCl2 wasn't a good idea.
SWIM has a glass stirrer and some paddles, but SWIM needs to shave the paddle down to fit in a 24/40 neck. the SS shaft has a different mount, so that paddle won't work.
SWIM has looked high and low, and can't find anyone who does teflon coating. SWIM was looking to coat the inside of a large pressure vessel. coating the SS stirshaft will make it thicker, which will lead to problems with the teflon stirrer bearing, but that can be addressed easily.
