I dunno, Swamp... you may want to try the Duco the guys in the Trad Forum suggested to me; it worked superbly on the spray paint when I was using the Gold Tips... I'm at a loss in trying to explain why it's not working as well on my ACC's.

Or, if you're like me, and all you truly care about is a little bit of personalized customization but more importantly that white cap to aid in recovering the arrow, you could always sand off the bottoms like I did in my last pic and glue 'em like normal.
