Oh, okay hairspray. Heard of this before, but maybe part of the bike-kit of US-motorcyclists since decades due to the loosely helmet-laws? Last time I visited the states was in 1993, think at least in AZ there was no obligation to carry a helmet. This and the permit to carry a gun impressed me lasting, maybe like the other way round the unlimited autobahn.
Good experiences with the glue, stays tight.
