I haven't used the LMI white glue, but I am interested in knowing what qualities make it superior (in some builder's experience) to Titebond.
There is a study out there showing LMI's white glue had a better sonic/tonal profile than regular Titebond original when painted on metal and evaluated against the other types of glue (Titebond White and Yellow, Polyurethane, epoxy, hide, etc). How that relates to something you can actually differentiate (1) on wood and (2) in a Guitar or a Uke is up for debate. A lot of folks swear by the LMI glue but their shipping is an obstacle when I can go a few blocks and pick up a bottle of Titebond. Titebond Original White AR glue shelf life is 2 years if kept under normal conditions indoors. I wonder why LMI's shelf life is so short?
Here's how to read the Lot number from :

How Do I Read The Lot Numbers?
The first character in the lot number stands for the last number of the year that
the glue was manufactured. The second character is always a letter, ranging
from A to M. We do not use "I" because it resembles a "1". These twelve letters
correspond to the twelve months of the year. The rest of the numbers in the lot
number are for internal tracking purposes. Therefore, a product with the lot
number 4C5268 was manufactured in March 2004.
