hey guys, i need some help with gluing a tip. the tip is a white diamond, the old ones before the formula changed. it is a smooth white plastic material, very similar to ferrule material. i've heard they changed the formula because it was difficult to glue. which is the problem i'm having with a friend's tip. i did one with 'special-t' cyanoacrylate and it popped off. the second i tried devcon 5 min epoxy and it also popped off. any recommendations on what glue to use to get this friggin tip to stay on? i've never had problems with any leather or phenolic tip before. thanks!
