Please Note:

Most parabolic mirrors will have 2-4 minor uncoated areas along the edge of the mirror. See photo 2 above for an example. These are caused by the clips used to hold the mirrors in the coating chamber. Note that these are not defects. A couple of these uncoated edge strips will typically be covered up by the clips in your mirror cell anyway.
