epoxy primer
 

what is everyone using for epoxy on bare metal before body work?

I use Axalta 2580CR. It's a chromate epoxy, so kind of the gold standard. Rumors are it will be discontinued soon (due to the chromate), so get it while you can.

SPI. Great epoxy for a fair price. Sands nicely if needed. I also reduce it and use it as a sealer before base.

Free shipping when ordered direct over the phone.

Just realized it’s you Luke. :)

SPI worked great for me

Using anything besides epoxy first is like putting a band-aid on before the cut

wouldn't the Band Aid offer protection from a cut?
There are other options depending on the situation.

your best bet is to stay with the same system all the way thru primer, paint and clear. Determine what you plan to use for paint and clear and use their epoxy

That’s really not necessary. Especially with epoxy which is so solvent resistant. The stick with one brand is pushed by the manufacturers to boost sales. It is not based on chemistry….

It's based on my own experience and also seeing failures when I was a jobber tech.
Not worth the risk. Do it right, do it once.
