No reception problems , even in heavy rain, but presumably will do some
time.
If the dish completely rusts over , so no longer smooth, but not actually
pitted with holes or distorted, would there bound to be received signal
loss associated with rust rather than paint?
What sort of paint over the front surface , when the rust is cleaned back
?
If actual rust holes , from thinned metal that does not survive rust
cleaning, then how to deal with that.?

The dish needs to be smooth or there will be some loss. If already rusted,
you should get a new dish. That is assuming you are using one of the small
units for Direct tv or Dish. The very high wavelength needs a smoother
surface than the older 10 foot size dishes.

The paint should be of the type that does not have conductive particals in
it.
