Debated between urethane and epoxy primer for a hood repair last month
I had a 2018 Civic hood that needed stripping to bare metal after a bad paint job. Couldn't decide between high-build urethane or an epoxy sealer for the first coat. I went with the epoxy because I heard it bonds better to bare metal and less chance of lifting. So far so good after sanding and topcoat, but I'm wondering if anyone has seen urethane fail long term on direct metal? What do you guys normally use for stripped panels?

My buddy Mike went with urethane primer on his '69 Mustang hood he stripped and within two years it started peeling near the edges where moisture got in. He said the epoxy stuff he used on a door panel later has held up way better even with the same topcoat on top. Idk if it was just his prep or what but that made me stick with epoxy for bare metal ever since.

Aw man, tbh I think your buddy might've just had a prep issue more than a urethane problem. Urethane primer is actually pretty solid on bare metal if you scuff it right and let it fully cure before topcoating.
