epoxy primers, all the same?

Here's the deal, i am currently stripping my 74 torino, and am going to have a friend paint it and help with the bodywork.

I got some stuff down to bare metal, and i read that you put epoxy primer, then bodywork, then a sealer, then paint. correct?

so what kind of epoxy primer should i use, are they pretty much all the same, and if not what are some ones i should stay away from, or look at buying

Thanks
Dubz

I've always liked PPG's DP series primers. I might not be familiar with what might be newer, but back about 10 years ago the guys in the body shop classes I took at the time seemed to think it was the stuff to use.

Ist of all you have it right on the procedure but if you wanted to go one step better use the epoxy as a finale sealer.

2nd: It would be a conflict for me to rate the epoxies and there are big differences. In hold up in salt spray tests and some, certain colors will not stick to bare metals, some don't want body filler put over them. What ever paint stores in your area have them give you the tech sheet on each type of epoxy they have and read.
if you have a question from the tech sheet I will answer for you.
Get tech sheets on all the brands in your area.
This is without a doubt the most important part of the paint job so spend the time to study.

so BarryK you would suggest

epoxy
bodywork
epoxy
paint

some people say to use a sealer on the bare metal, is there advantages to this, or why do people choose to do the primers differently?

Epoxy
Bodywork
2K primer--as needed.
epoxy
paint.

When they say sealer most would be referring to the epoxy.(slang)
You would never use a urethane sealer over bare metal (except E-Coat).
Unfortunately there is an intentional lack of educating in this business one because the paint reps and the jobber help today
are not what they use to be years ago, its called saving money. Also the less info given to you when you have a problem its your fault, not theirs!

LEAD or lack of CHANGED EVERYTHING!!
Most people when will recommend what they have used or herd about 15 years ago. Lead was removed in the early 80's and where an enamel might be good for 8 years it dropped to 2 years at best along with lacquer but you will still have someone tell you this enamel job I did in 1985 still looks good only because they don't know the real facts. DP in early 80"s was the best epoxy out there hands down but it had lead, now the White can't be used on bare metal, so things change big time in this business.
Paint companies make tech sheets on all their products, so its always advisable to read instead of asking a question to the delivery driver or counter help. Don't get me wrong some countermen and paint reps really know what they are talking about but they are fast becoming a minority in this business.

I have also been partial to PPG DPLF series of epoxy primers. PPG K36 urethane catalyzed primer/surfacer can be used as a sealer when the proper activator is used.
