Rustoleum NeverWet shows a Satellite Dish on it's packaging:
Yes, it shows a DISH which is painted metal, but not a DOME which is plastic. Under the pictures it says concrete and wood, but the text under the dish is cut off. Other product pictures show the word "metal" under that picture.
The product information says it's compatible with "most plastics." It would be interesting to know what kind of plastic is used for the OP's dome, and whether NeverWet is compatible with it.
I don't know what kind of plastic is used by KingDome, but I know that when I used KindDome's treatment on my KingDome dome, it made the plastic look and feel terrible: it looked like the treatment actually attacked and softened the plastic.
