Chris,
You've picked one of those thankless jobs on the coach!
The entire cover assembly has been an object of frustration for many years.
The trim & screws were not meant to be the waterproof seal of the seam.
The butyl rubber underneath is supposed to do the job, the trim & screws
were supposed to be cosmetic. The system is not as reliable as they had
hoped for.
I am trying a new silocone membrene material that I hope will be a better
sealing system. The stuff is used to seal seams between concrete buildings
and seems to work well. It comes in several colors and looks pretty good.
If you are interested, give me a call.
As far as patching the origional system, I have used #10 phillips panhead
screws and they work well unless you tear off a head forcing them in place.
You may want to cut a groove with a steel screws first. I would not use
rivits but if you do use sealed cap style rivits, you have less chance of
them leaking around the ball.
Hope this helps,
Jim Bounds

>i started replacing the metal screws to stainless on the roof ridge
molding. im using #10 3/4" long . the trim has to be countersunk and the
screws have to be trimmed (take off 1/8"). i am also putting silicon in
the holes and removing the loose caulking . i will coat the remaining
caulking with pl5200. i wonder if a panhead screw will work with some kind
of rubber washer, or use big pop rivets ?
