I used aluminum as well. I used "Shoe Goo" to stick it on.
I thought that one the alum. whore out, I'd just replace it with
another pice. It's been on there for a good 15 rides.
Now if I can just get it off???
I used die protector (tough plastic) on another KX I had.
It worked good, but kept ripping off the zipties, and wire....
