Red n Tacky is an EP (extreme pressure) grease with a "high level of EP additives".
These EP additives contain sulphur which will attack brass and bronze components.

In addition to my day job, I also farm. We use red'n'tacky as well as some other EP grease lubricants from a well known agriculture equipment manufacture that happens to paint there equipment green.
We like the red'n'tacky when as it does a good job a staying where you put it. When it comes to brass and other yellow metals, you only really run into problems if those metals get hot under operation.
A good example is a small gearbox used for one of our grain sample unloading augers. It has an exposed worm worm gear, no oil bath, so grease is the only option. The worm gear is brass, and we've been using red'n'tacky for as long as it has existed and haven't noticed any corrosion of the metal. This auger is was built sometime in the 50's and is still running quite well today. With red'n'tacky the grease stays put, and we were able to reduce the lubrication intervals for this gear box. In this particular situation the red'n'tacky also resists water, and other foreign chemicals better than what we using before.
We were told it is okay to use EP lubricants with higher levels of additives because this gearbox doesn't reach temperatures over 200 degrees. At higher temperatures, the EP additives will begin to react with yellow metals.
