I don't think any of the "Centers" have skin paint.

They all do. And thus they have weather.

Then you have operated in a different flight control system I have for the
last 35 years. A friend of mine died because he lost his transponder and
Washington Center didn't have his skin paint.

There could be several reasons why a skin paint is not displayed on a
radar scope. The fact that a particular radar does not pickup
enough energy from a primary return to display it does not mean that
it is incapable of displaying any primary returns. The reason we have
transponders is to make radar returns more powerful. Aside from a
return too weak to display, the radar operator has to configure his
radar to display primary returns or secondary returns or both. If the
radar operator filters out all but secondary returns (transponders)
then of course, no "skin paints" or weather will be displayed on his
scope.
