1- Fast tak is not tubular cement. 2- Zipp actually recommends using a substance called "Goof Off". It's a spray on paint/vandalism remover.. They have tested it out and it doesn't affect the laminates, resin, etc of the carbon rims. Works great on Aluminum too.. Miracle rock is okay, but messy.. Goof off is cheap, and best of all, supremely toxic. Be sure to use in really really really well ventilated area.
