Howdy, can use some reference for the next project on the list sealing top
rails.
Sealing the drivers side upper rail is priority as its dumping water by
the back end cap connection and I might as well do passenger side while i'm
at it before it needs it and before it gets cold.
I've been reading and clearly see silicone is NOT approved as are self
taping screws due to the threads not sealing,
I see Jim B. did a few articles on his site but I'm not sure what is the
current best solution/procedure using "3 beads of bond-n-seal and the rails
are again sealed".
Magazine issue 64 said Butyl rubber.
Photos page has some pics of what the gap looks like under there.
So rail remove I can do, but seal with what and how? Then re-attach with a
special screw without threads on the gap?
Thanks team.
