I've used Gorilla Glue,Scott Grip glue,Carb spray,Brake cleaner spray and Spray paint before. They all work good except The left grip all ways tends to turn at the end after a few rides and thats even using wire. I like Gorilla glue but it is hard to scrape it off on knurled throttle tube. After the last time I used it on the throttle tube I liked to have never got it all off. Now I just use Carb spay on the throttle tube and it works great (No turning) I guess cause of the throttle twisting it self. I have just put on new grips yesterday and bought a can of 3M adhesive spray which was $17 a can thinking this is the stuff I was looking for. I didnt use it on the throttle cause the carb spray works for it but followed the directions for the 3M which said to spay the surface in one direction and let dry for 3 minutes or until tacky and spray in the opposite direction and let dry til tacky. Then spray the surface that you are matting to (which would be the inside of grip). Slid the grip on and got it lined up and then put uniforn pressure on it with my hand for about 5 mins and came back an hour later and put pressure on it. After doing this I still put three strand of wire on and let sit and dry til today. Checked this afternoon and felt of the grips and they seem to be on good but at the end it seemed it wanted to twist. I stopped when I seen it was turning a tad at the end(so that I wouldnt break the bond). But the end is what gives me trouble. I have the Flexx bars so the handle is not knurled but slick. Maybe the adhesive is still curing and needs to dry some more. I will not be riding it til sunday so that will give it two more full days to dry.
