Can base units be removed?
Three easy steps for base removal.
Yes… Base (the part attached to the vehicle) removal is easy and replacement bases are available. This is great when if you buy a new shield, bike or vehicle and want to take your mirrors or mount with you. The new base units come complete with tape installed. The tape is not available separately since a special tape enhancer is used on the base just prior to the tape being applied to the base.
Step One
Remove the mirror. To do this, remove the base fastener and the entire assembly. This includes the mirror assembly, which includes the base cap, arm, and mirror. Note the Allen key slips through the cap port.
Step Two
Warm the base. It is much easier to remove the base when it is hot. An easy way to do this is to let it bake in the sun for an hour before starting. Another option is to preheat the base using a hair dryer on the low setting. Caution: Hairdryers vary in power, so be careful not to overheat the shield or mirror components.
Step Three
With the base still warm, peel slowly, starting along the edge. If you must use a tool to start the base removal, use dental floss or a smooth-edged tool. Avoid using a razor and be careful not to scratch the shield or vehicle. Go here for replacement base sets.

The base units are affixed with 3M High Bond tape. The taped base holds tight but can be removed from the shield. Replacement bases are available.
