I would go to a good high build primer and then paint after that.


Which is NOT epoxy resin.

Resin, by itself, is quite brittle, Will chip loose, Will crack,
and will NOT serve as a seal coat (for very long).

Sand the fairing material smooth.

Prime (per above) and paint.

THe only way to seal the fairing compound of a male one off is to "tight
glaze" the compound with Rojo after the hull is fair, then shoot high
build primer followed by LP.

Lots of sanding in between.

Anything less and you are kidding yourself.
