Here are a few ways to be notified of upcoming boat detailing classes...
Sign-up for one or both newsletters. The PremiumBoatCare.com store site carries different products besides Marine 31 and the Marine 31 site store is more dedicated for Marine 31 products plus lots of tool, pads, towels and accessories.
Sign-up for the Marine 31 Newsletter
Sign-up or the PremiumBoatCare.com Newsletter
When the details for the boat detailing class are finalized they will be announced in the newsletters.
I'd also recommend "Liking" the Facebook pages for the above.
