I appreciate that and I agree. However I did find on the Park Tool site: "Carbon gluing surfaces have special considerations. Most manufacturers of carbon rims state that acetone is acceptable for cleaning the gluing surface. Contact manufacturer for their recommendations. Abrading the carbon can be useful for cleaning surface. This is especially true if there is "mold release" on the rim. This is a slick substance that allows the carbon to come out of the mold during manufacturing. Use only a medium grade sand paper or emery cloth (approximately 120 grit). Do not abrade down to the fibers themselves. Clean with an oil-free solvent after any sanding."
So maybe that's good news considering I prepped a set already using acetone.
