Hey Dan! Hope to see you in Pensacola. Karen says you rented a house. Tell us when to be there. Dean Siracusa put together an updated maintenance manual for the 200. Electronic version. This is from there:
• Door Seals – Inflatable Systems: Bob Fields Aero-cessories. Phone: 805.525.6236 – http://www.ultimatedoorseals.com
Mine are standard foam. Fairly new. I can look at logs for source if you need.
