Booster has a shelf life. My seamoon lost most it's potency around the 8 month mark, and completely after a year.

Anyway Tyce, boosting & spein gluing is unapproved under ITTF Rule 2.4.7 and Regulation 3.4.2.2
More importantly , boosting & spein gluing is illegal & potentially criminal under common law
