Service Bulletin/Repair Instructions
Winnebago is implementing an improved sealant application process to enhance durability, long-term maintenance, and vehicle appearance. Moving forward, SikaLastomer®-714 will be used as the sealant for roof-mounted components, including roof vents, skylights, and TV antennas. This change eliminates the use of self-leveling sealant around roof components, providing a cleaner, more refined appearance while reducing concerns related to cracking or discoloration commonly associated with traditional sealants.
