My dad invented Top-Cote along with whole series of lubricant/protectant products for saws, routers and guns (Bore-Cote...) under his company at the time, Sandaro (product lines was bought out by various companies). Also some to be used in military applications for munitions and arms. Top-Cote was a replacement for nasty cosmoline. You are correct if I recall correctly, it is uses both wax and Teflon in a solvent. Top-Cote worked much better to prevent rust, in particular in high salt/humidity environments, and much easier to remove. I often use it on top of my mill or table saw when not in use. Also for metal tools, that I stick away.. I have used TopCote (now GlideCote) and Boeshield T9 for extended idle time. I spray a layer on after a good surface cleanup and not wipe it down after application. Both products have worked well for me but my area is pretty dry. It appears most folks have the best luck with TopCote in high humidity environments. It's a lot like cosmoline in that it leaves a waxy film. You need to give it a wipe down with mineral spirits to bring the equipment back into service.
