In response to the question,the cans of amber shellac did not have dates on the bottom. They looked different and if memory serves, I believe they are a couple years newer.

I work in a paint store so I checked our cans of shellac.
Sure enough the cans of clear shellac were bulging and they
looked like they were ready to blow. They were dated 4/05.
Needless to say, I immediately yanked them from the shelf.
The cans of amber shellac were fine.
