The plastic voltmeter that was stuck using double-sided tape came adrift on the last ride, heat caused the tape to release so I did some research on glueing it back onto my alloy dash. What I found was Selleys Power Grip, and it says Glues all Plastics "asterisk" small print, not polyethylene polypropylene or PTFE. Who knows what the gauge case is made out of so gave it a go and we will see. It's supposed to set in 30 seconds, that didn't happen.
 
I have spent years doing huge silicon joints in glass walls, but I also have had issues using it generally as a glue. Just not going off on occasions and it's hell to clean off if that happens.
 
It will be Polyprope Vince, PP is the worst plastic to find an adhesive for. I've tried every product known to man, and PP defies them all. If you can scuff up the PP surface it may help, but PP by it's nature leaches a lot of oil out of it, especially when warmed/heated and bleeds under the adhesive. Thus falling off. If you want to send it to me, I can coat it with PVC, and that will adhere, and stay put.
 
I am surprised, the glue worked FOR NOW. It will get a test on Sunday's breakfast ride, vibs heat and the usual loads.
 
It's mounted on a bit that holds my Cigarette lighter power outlet that's too wide for any mechanical fixing, cable tie etc.
 
I did in the past use silicone to seal the joints of boiler flues (chimneys), these were mainly stainless steel and about usually about 300/400mm diameter and single skinned, I didn't believe that it would withstand the heat but it does.

Some silicons are better than others with heat. I used Dow Corning for hot areas.
