I have a Dashcam on the windscreen and a SatNav on a smooth plastic plate on the dashboard.
Both are held in place by suckers, as is usual.
However, they both have a tendency, particularly in hot weather, it seems to me, to lose their 'suck' and fall off at inopertune moments.
I was wondering if some kind of grease or oil on the sucker, instead of the usual saliva, would provide a permanent (ideally) solution or, at least, a longer life than at present.
Any ideas?
