If you must "paint" the top of your Diamond, you can use polyester resin,
hardner, and a white pigment "coloring" additive.  These products can be
found at marine supply houses and are used for marine repairs.

It isn't "paint", but rather two liquids you mix together, like epoxy.  You
apply it like a paint with a brush [or professionally, with an air paint
gun]. The chemicals react and harden into the "fiberglass" surface [Gelcoat]
you find on your Diamond antenna, boats, hot tubs, etc.

If your radome was cracked, you would want to also use fiberglass mat to
rebuilt the strength of the broken section.  Although these URLs explain
boat hull repair, the process of making fiberglass repairs is summarized
nicely, including caveats for inexperienced glass workers.

P.S. A can of white Krylon would probably provide the same esthetically
pleasing results, with a lot less work.  My reply is more along the lines
of:  "for educational purposes only"!
