Zinsser Shellac Date Codes

The batch code on the shellac should always be a 6- or 7 digit number, beginning with a letter. For example: S01231D

The first number after the letter will be the last digit in the year of manufacture
The second number will correspond to the month
The third and fourth numbers will relate to the actual day of the month.

In this case a batch code reading S01231D will have been made in the year 2010, in the month of January, on the 23rd day.

The Bullseye Shellac will have a shelf life of three years.
