Re-sealing Winnebago radius roof in "J" channel

Earlier this year I redid all the J channel on both sides as well as the front cap to the roof on my 2003 Itasca Sunova. Until then I had only been doing the sections that had lost the bond between the roof and the channel. I used Manus Bond 75AM available on Amazon. As memory serves I found Manus recommended here on the rv.net forum or it could have been IRV2.com forums. Of course then I finally found a new 2020 Vista to buy.
