3m double sided molding tape could be good
This may seem strange but was fixing my roof molding on my Dodge Van and had to get some double side adhesive tape to attach back to roof channel. This stuff is super sticky and really takes a hold for attaching things to metal and such. I am thinking somewhere in the bike world I could use this stuff and plan on keeping it around shop. Right off the top I am drawing a blank but the holding power of this tape is tremendous, it would not hold a bottle cage but it sure could be of use.
