all these methods work, paint, glue hair spray, but to repeat the post above a little stronger, WIRE TIE THEM. and if you dont know how then ask someone to show you in person the first time. i watched a guy last year pull a grip off mid air over a 90' triple. as you can imagine it was all bad. guess what, no safety wire on his grips. and while were at it, you ever see a guy lose a foot peg mid triple? i did, because he didnt check to make sure the codder pin was through the bottom of them.
ok off the soap box now, i just hate seeing people get hurt, and when it was for a stupid preventable reason.
