It happened again this past weekend. I walk into a store to pick up a can of Zinsser amber shellac. Out of the five quarts I found on the shelf, not one was still usable, according to Zinsser. In fact, one of the cans was dated 2007. Shellac is good for three years from the code date printed on the can. Don’t buy old shellac. That’s just asking for trouble.
If you need to know how to decipher the date of manufacture of Zinsser shellac, click here to read a post I did the last time this happened to me.
By the way, the can shown in the opening photo no longer contains “fresh” shellac. I wouldn’t use it.
