Epoxy orange peel

Hello all,
I'm new to this but will be asking lots of questions later, right now i'm testing out Epoxy on wood with a white pigment
I'm starting a Barrelback build and want to get ahead of the problems before they get ahead of me.
So
West Systems Epoxy mixed 5:1 with 5% pigment and rolled on then tipped with a fine new brush
All good so far,
Amazed how liquidous the mix was and how far 240ml of the mix went
Vertical surfaces were a problem it just runs if laid on too thick
Biggest problem is that it well you seem to call it 'cratering' I'd call it orange peel
sanded it all down and tried again wondered if it was grease traces so was meticulous in preparation
Still getting the orange peel
Why?
can anyone help with more experience of this

Cratering and running are generally too thick an application and a dirty and/or too smooth a surface.

Epoxy is not paint, so you're not likely to get a perfectly smooth surface from it. Even with pigment it will need to be top-coated with something to protect from UV.

I use a product called Dupont Final Kleen before any coating. It will remove oils and waxes and prepares the surface for coatings.
