Painting over Gluvit

[hopper3333]

I applied some Gluvit over some leaky rivets. It is an epoxy and recommended to paint over it to avoid UV damage to it. Should I be using a primer first, and if so what kind? I am wondering about primers that work over epoxies.

Thank you for any insight!

It must be sanded with fine paper. Then prime and paint as the paint recommends.
