That is my experience with BP 262 also.
I had half a gallon left when I quit pouring when the Pandemic hit, and is still good. I just poured a bunch of 5" swimbaits and Zoom craws, and all I did was stir/shake it and add heat stabilizer to each new batch.
No caking, and very little sludge in the bottom of the gallon jugs. I did shake it every six months, or whenever I remembered.
