I purchased some tank protectors from Touratech so my seat bag straps won't mark the edges of the tank panels. http://www.touratech-usa.com/Store/...protector-tail-section-BMW-F800GS-F650GS-Twin They came with a tube of glue which looked and smelt like silicone sealant. But when I used it as recommended the tank protectors just slid straight off. I put them back in place and held them with tape for 24 hours but I could still easily remove them, so I gave up with that idea. Any suggestions for a suitable glue which won't eat plastic? Also it has to be able to fill the void between the tank protectors and the body panel, as the aren't a snug fit.
