DW has asked me to install a few
towel jams in the bath to make up for the lack of towel bars (really no good place to put them). She has them in our home kitchen, and it's a favorite thing of hers.
We agree that the best place to mount them would be on the fixed panels of the radius shower. But that glass is a pebble finish, and (of course) is just shy of perfectly flat.
The double-sided adhesive they come with was useless. The premium double-sided foam tape I had on hand lasted less than three days on the road. I'm currently trying Nano Tape, in hopes that the jelly-like consistency will get better purchase onto the pebbling. (Yes, I alcohol-scrub the glass first.)
40 years in hobby modeling gave me a pretty good adhesives repertoire, but if this stuff doesn't work, I'm running out of ideas. I'm sure Liquid Nails would do this job in a jiffy, but I'd like to avoid going nuclear if somebody else has a favorite adhesive that would handle this job without permanently disfiguring the glass.
