Painting Rod Boxes

[reodds]

The rod boxes on my '84 V20 are horrible looking, and replacing them is not financially feasible right now. I successfully repaird all the cracks and holes with expoxy and fiberglass, and the external portion now has a nice even surface.

Has anyone used Krylon Fusion paint on them to restore the appearence? I figured it is a paint specifically made for plastic, and since the boxes are not abused by foot traffic it should work.
