Here's the scenario:

I painted my car about a year and half ago (bc/cc) and had some runs in the clear on part of the car. I ended up sanding these down and reclearing last fall. I went to wet sand and buff the clear and in doing so I ended up going through the top layer of clear and there is a definite dull 'ring' where the transition between the layers occurs. I don't *think* i made it down to the base.

I am now wondering how to handle this. I plan on reclearing the panel, but I'm not sure if these rings will show through. Should I use a blender on this area (I have a can of UPOL handy) before I clear?

I figure if it is down to the base, I will need to put a layer of clear on first anyway so it's worth a shot to clear and hope that the layers all melt together and disappear (probably wishful thinking).

It seems to happen, when you break through new clear into clear previously applied, it will show as you have mentioned.
But if you reclear the panel, I think they should disappear. Try taking a rag or something and wetting the area with some water, to kind of simulate the clear, and see if your rings disappear. If you only broke through to the previously applied clearcoat, I think all that will be required is wetsanding the panel, and reclearing it, and put on enough that you hopefully won't have the breakthrough occur again.
If you are down to base however, likely blending some base over the area would be required (even better epoxy prime it first to elimanate lifting problems that may be likely to occur). Did you notice any color in your water when you were sanding that would indicate hitting base? Normally its pretty easy to tell when you've gone far enough and hit base.
