Some really good info here, Does anyone know if Menzerna has a shelf life.
I have some that's around 8 years old.

Thanks

That would be awesome. Thank you sir!

Yes. I was having issues buffing, so I made a new arbor (earlier post) with 1" shaft and larger wheels, and ordered new compound (switched down to medium/fine vs fine/extra fine). I should've known it was the compound, but I ended with a better/smoother/quicker/more stable buffing arbor.

Should be fine. I would shave the end to remove any embedded dirt from storage before use.

I had some that after 8 years or so was no longer behaving well, despite chopping off the end of the bar to expose “fresh”. The problem was worst on the finest grit that seemed to have become hard and dried out. I did some asking around and found I wasn’t alone. I replaced all my Menzerna which solved the problem. YMMV!! I now store them in a zip lock freezer bag.

This morning, I opened one of the drawers of my tool chest and then the others and found the contents of all of them covered with a layer of cotton fluff. That stuff gets everywhere. The 1/8" gap at the tops of the drawers wasn't small enough to keep it out. I had a small project added to today's list.

Another reason I switched to using wet automotive compounds.
