So was spraying engine compartment with base after epoxy sealer was going down. I got about halfway through and electric went off. Tank pressure didn’t get me finished. I can’t get back to for a week or more. It’s in a garage but not an ideal environment. Can I just wet sand base and reseal on top of it or does it need to be sanded completely off? It as worried as going over the base already there but the sealer that wasn’t covered.
