Folks, Don't dismiss Tony Moss' suggestion of the glues used on car mirrors. It is pretty good stuff, I only wish I could find out what it is! It will withstand air temperatures of > 40C and continual exposure to direct sun for years.
Some advice from having to replace a stick-on car aerial for a mobile (=cell) phone that may be relevant to gluing gnomons: clean the site with isopropyl alcohol. When you have cleaned it, clean it again. And then a third time. Use paper towel. The first time I replaced the aerial, I only cleaned it once, and the aerial parted company from the windscreen! The techos at the shop told me to clean the windscreen three times. Worked fine. Many people seem unsure of the modern adhesives, probably from bad experiences with unsuitable glues. The range of industrial adhesives routinely used for exposed components, and high strength joins is amazing. The difficulty is in locating the small supplies that a "normal" person would use.
