I've searched drip rail on the forum and only found shaving them. I want to go the other way and install them. I sand blasted, etch primed and painted the mounts. Originally they come with a paper thin gasket on the back to keep them from rubbing the paint and seal the bolt holes. I'm thinking about thin glass setting tape (1/32). This may eventually streak the paint though.
I've been told permatex, double sided tape or to just use nothing at all.

A good quality two sided emblem tape should do the trick.

I don't think emblem tape is water proof enough for this application. Also I don't want the installation permanent.
Thanks for the reply.

The 3M tape I use is made of a foam type rubber. I would think it should seal out any water when pinched down by the screws between the roof and drip rail.

Anything bolted down or stuck to the paint is basically permanent. Once it's clamped down for a while with whatever you use it sticks to the paint anyway. I used non sticky foam on my 77 and when one rail had to be removed 2 years later the paint came off with it around a couple of the bolt holes. when the retainers were new they had a single sided sticky foam tape on them. If you don't use anything under them then they won't keep the water back and will be useless. I have used rtv on some rails and it worked great, but I never planned on them being removable so I can't tell you how they'll come back off and clean up.

When I reinstalled mine, I used 3M weatherstrip adhesive. Worked great. I ran a small bead down the center of each rail and put a dab on each screw hole to seal the holes when the screws were installed.
