epoxy primer

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.

I’ve seen plenty of failures but never due to mixing brands of epoxy and urethane paint. I’m sure the manufacturers and jobbers like to use that excuse because it absolves them of all liability….

Quality epoxies and urethanes have no compatibility issues. Quality being the operative term…

not an excuse, it is real.
The main thing for others is there is no reason to take the chance. It is real easy to stay in the same system throughout and eliminate one other avenue for things to go wrong. Zero advantage to mix. People try to be a chemist or save a buck. A proven system that has been designed, developed, tested and beta tested is always the best option.
