My paddles - about $25 paddles - have 2 layers and only the top rubber layer was partly loose and I glued them back together. Not sure if this is the proper application to use the glue but some of it didn't stick too well.
Works fine, difficult to apply
The glue works fine, as do the sponges. My problem is dispensing the glue from its container. The glue would not come out and I had to repeatedly remove the top, this caused me to use a bit more product that optimal and made the whole process messier than it needed to be.
The glue works great. The rubber stayed on after one application and I have been playing since and have no problem at all.
3x price of btrfy
not used, too pricey
