Topic tags/keywords: shellac zinsser rust

I’ve been in the (bad) habit using old zinsser shellac cans to store cut shellac. I opened my cabinet to find a bloody mess. Most of the cans were stuck to the shelf. I cleaned up and noticed that a shellac can had rusted through on the bottom. Admittedly the cans were probably to old—date stamps of 2012 and 2015. (date decoding link: https://www.popularwoodworking.com/woodworking-blogs/flexner-on-finishing-blog/user-unfriendly-zinsser-bulls-eye-shellac ) Still I didn’t think that the cans would rust through. I’ll start storing cut shellac in some old canning jars (so I can drop them and have glass mixed with shellac on the garage floor :) ).

Thought this might help someone. Look at the date stamps on the cans and think twice about using very old ones.

I had that happen – I have everything stored in a metal cabinet with lipped shelves which captured most of the spillage so the mess was somewhat contained.

I’ve never had it happen to shellac but to paint cans, one the other day was only a couple years old and had been stored in the house.

Ditto on latex paint cans!
Had quart of red accent paint, removing the top actually removed about 1/2” off the the entire can and yet there was no visible evidence on the outside of the can; maybe if I waited longer there would have been.
