I purchased a heavy, sticky bottom, dished disk thingy (approx 6ins dia) which enables me to hold a sat-nav on top of the dashboard and it's worked superbly for the first 9 months or so, not moving at all during heavy breaking or accelerating. However the stickiness of the base seems to have degraded and I now have to catch it if I accelerate, particularly up a hill. The combination of a heavy canvas toroid filled with what maybe lead shot, a sticky base and a smooth plastic surface to fix the suction cup to was very successful for a time. However :-( .
I don't have the original instructions or name of the product.. I bought it in a "motor mania type shop" some distance away.
Does anyone know if it's possible to treat it in some way to recover the stickiness? perhaps wash it? or re-coat it with something? or do I just bin it and look for another one?
