I tried the gel years ago, it looked great and bonded great, but it didn't hold up with the moisture changes of climates, the vibration of the glass caused it to come loose. I've also tried the Lock-on flex glue, for looks it's great, but don't try to play it, it's as dead as can be
, not sure that stuff is good for anything? The best I've ever used was the Simple-Fix glue, it went on in a thin bead and held like no tomorrow, completely clear, but they outlawed the sale of it in this country, so you have to get it from Australia and the cost to ship it here is outrages with a 4 month shipping time!!
