Hey guys, sorry I am sure there is other threads but didn't see any. I am having problems getting some of the Kamui blacks to stay on. I have no problems with any other tip but these. I do install these probably 3-1 over anything else but these are the only problem. I have tried scoring the glue surface, tried a skin layer of glue let dry and then sand. The last one I tried some 10 minute loctite epoxy and it popped off in just a few minutes of use. This is starting to dig into my pocket with the re installs. Any help?
