I have used 2K primer only for about 20 years with zero failures. Sand the metal good, then metal prep 30-60 minutes before primer, and NEVER has adhesion problems. The only time I would consider epoxy first is if it will be left in primer and exposed to the weather. As far as wetsanding, I do it on every job, and then seal and paint. No problems with this in 20 years of full time work.
I know I am a dinosaur... but I guarantee my work for as long as they own the project. That takes confidence. I like Marhyde's Ultimate Primer.
Oh yeah,I remember that ultimate primer it was pretty darn good stuff and cheap too...I used itwhen it first came out and for a few years after that ..do they still make it
