Why not call Santana (800 334 6136) and ask what they recommend? That's what I did when the 7 year old Mavic rim on my Noventa shot craps. Steve Liese is in sales at extension 13. I've found them to be very helpful once you make contact with an actual person.
Incidentally, I understand that FIR is out of business so I'd be cautious about using one of their products.
