I sometimes use expandable foam as glue as I have installed amps in between the body cavities and silicone with time and vibration will fail I have found that the sticky foam stuff is great to stick stuff together in tight places and to prove it I installed something for someone in there truck about 5 years ago and to this day that panel has not faultered in any way....so if you need it stuck in place for a long while use the yellow foam stuff and ohh yeah i let the item set over night before i attached anything heavy to it.

 

neat...but that foam makes noises worse

 

foam is supposed to deaden noise, i dont see how it would make it worse.


nice catch thouhg on these "glue discoveries"
