Zipp’s Matte white and Matte black decals also are still available. Each decal kit has seven decals sufficient to cover one wheel and two matching valve-hole decals. Note: Before applying the decals, make sure the rim surface is free of dirt and debris. We recommend a gentle wipe with acetone or rubbing alcohol. Peel the white backing sheet from the decal, orientate, position and gently press the decal onto the rim surface. Starting at one end, remove the surface clear cover slip and then work the decal into the dimples using a 3M squeegee.
