Whenever I order a Tech Spec I ask them to use the aggressive glue.
I clean the area with alcohol swabs then heat to warm the bike and the Tech Spec.
Then apply. The claim to fame for Tech Spec is that they are removable and you can reapply.
WARNING: If you get the aggressive glue be sure you get the placement correct the first time because the glue they use is VERY strong!! but they can still be removed but it is hard and sometimes the glue separates from the rubber.
Guess I need to reorder with the good stuff
