I put a Kamui Blk Medium on a Joss this week end at a bar I never do this normally but the guy wanted it now and I did it by hand, I used Gorilla super glue, the tip would not stick, I did prep the back with glue prior and scored the back and pressed the tip at my store before going to the bar tournament.......after 30min being put on at the bar it held........the guy play's with it 45min. later about the 6th hit " BOING " there goes the tip...I have never had this hard of a time to get the tip to hold...I normally do them only in my shop.....what is the norm for waiting to use a new tip and my glue is about 7-8 months old, .... I seen on here people liking Loctite ultra gel with the black wrapper.......
