Don't put anything over the epoxy.
When your ready to work on it again just scuff it good with 180grit and apply filler or your 2part primer.
Nothing is going to beat epoxy for protection except better epoxy...

Edit: if it was me I'd shoot 3 coats of SPI black epoxy and be done with it. Let it sit out it won't care. It has uv inhibitors.
