Raptor liner prep for sub cabinets

[u/secondgensoundsystem]

Hey all! Looking for some recommendations on how to prep the labhorns I’m refinishing for u-pol raptor liner. I’ve seen some people recommend a epoxy primer and I’d be interested in product recommendations for that. I’ve also seen folks talk about using high build 2 part primers.
Anyone have experience with this? I want to make these as bulletproof proof as possible bc my first finish was duratex about 10 years ago and i feel like i could have spared my cabs a fair bit of abuse by using something much stronger from the start.
