That joiner strip between panels!!

OK, so my camper is riddled with joiner strips, where the roof comes over and meets the wall, and the front cap comes to the roof and walls, and many more places.

It looks like one inch material, over butyl strip, and screwed through holes in the aluminium strip, then a thin plastic piece fits inside the shape to cover the screws.

Not for one instant do I believe that the plastic piece prevents water intrusion to underneath, but then I wonder if it creates a water pocket inside, and just tries each screw hole until one or the other leaks.

Then sometimes, the staples that held down the roof didn't quite match up with the placement of the strip.. and once the strip was on, sometimes the staples are not under the strip.

So.. my question to the group. It's a 1 inch wide strip. Is there wider strips perhaps. Maybe 1.5 inches, or even 2 inches that better protect those gaps in the outer surface that could be fitted? What do top quality rigs do and can we retrofit their methods and materials to our rigs? Resealing is not the answer, because we reseal when we find a leak, not usually before. What can last for 30 years and still do a good job?

Thanks for thinking.. Mike
  • Depends on what You want the finished job to look like and how well You want it to perform!

    Of course there are some who will have plenty of time to do the job and others who just want to get on down the road!

    Eternabond is a great product when applied properly and a real pain if stuck on haphazardly !
  • OK... Eternabond might be the answer...

    For those that have put Eternabond across joints... does one just take off the original strip and the screws out... seal the screw holes, remove all traces of the butyl strip, and then lay on a strip of eternabond instead? Or just lay it right over the original strip and cover it up?
  • I pulled all of my aluminum trim strip and resealed it. Bought new plastic screw cover for everything, too. I almost got it all sealed. As you surmised, water can enter under the screw cover and migrates around and along the screws. I went back and sealed all the screws, adding a piece of Eternabond tape to the joint where the trim meets my metal roof. No more leaks.

    If I was to do this again, I'd use a strip of Eternabond Doublestick tape under the aluminum trim. When you screw through it, it seals the screw and hole completely.
