I bought a month ago a 2000 Adventurer that the roof radius peeled back about 10 feet in a wind storm last week. Reading tons on here about different sealants it seems like Henry 212 & Proflex are the concensus. Both are silicone. However the Winnebago sealant chart for my year & model calls out 07889-20-000 which is Manus 75 an urethane. Which should I go with? Thanks!
