Epoxy primer can go on bare steel and does not require self etching primer (self etching primer is old school, barely anyone uses it anymore)
2K urethane primer is usually high build primer that you put on 2-3 heavy wet coats after you've done bodywork/filler and then you block sand it starting with 180 and finishing off with 400/600 wet.
There is primer sealer (you just reduce epoxy primer) and use it as a sealer, you can do this with SPI epoxy. You put on very thin wet coat over entire car before you paint, to fill in any small sanding scratches (400 grit) and to provide better adhesion for your topcoat (paint)

Don't use etching primer, use epoxy. FYI, a lot of epoxy's are not compatible with etching primer. (Be sure to read tech sheets for products you are using!)

adding to Silver's post....consider contrasting colors epoxy vs blocking primer (i.e.black vs grey), that way you'll know to stop blocking BEFORE busting through to bare metal.

  If I topcoat my urethane primer soon can I not use epoxy? (Or vise verse). I'm trying to just use 1 type primer.

Ive gone through this threa before. and ,a friend of mine had a rusty old challenger and the car was in bare metal but sat around for a couple years outside, and was a rust nightmare.    Our shop did not want to tackle that job.    so a back yarder who actually knows a little about painting.  used the eastwood cover it all up  rust block primer..  well its been ten years   until it started showing a little rust,   and im not sure its from the outside surface rust.  anyway   the stuff impressed the hell outta me. 

                          If you just want a protector to put on until you can really get in ther an do it all up right id suggest the eastwood all in one  rust block, best stuff out their besides bouey paint.

Tom do you mean Rust Encapsulator? (That's what I started using.)

                  I believe thats what he used.    It blocks off moisture and oxygen so rust cannot keep rusting.  But you have to topcoat it.    Ive used por 15  without topcoating it and it will rust like a pig. I would go with the eastwood rust encasulator.  still gring  da or something to get it as clean as you can. first  then aply the stuff and  then do your   thick prime and paint job.

Well this is good news, the roof is striped/sandblasted and coated with that stuff. The whole reason for this topic was to figure out how to proceed from that start. I've read much on primers both urethane and epoxy from several sites and mfg's spec. sheets.

I've tried Eastwood Rust Encapsulator and primer didnt seem to stick too well on the outer body..

Could always go to MAACO.  I prefer Dupont Centari single stage. Do they still make that? LEON.

Yep. Last I checked, they still do Leon. 
However, given the heat & humidity where Neal is from is why I suggested a urethane such as ChromaOne. Centari is good as far as acrylic enamel goes, but a urethane based paint is better.

I grew up on Centari and still think the world of it. Don't forget the performance pack which makes Centari like urethane.

No way!    They still make the performance pack?? That's great!! I remember using that stuff with Centari, painted many cars with it. 
I thought for sure it would have made it's way to extinction already like Lucite.

  I see Kirker has the same, Acrylic enamel with urethane added....   and good news my supplier will loan me a 3M adhesive gun for my patch panels. 
  Anyone use Evercoat's Quantum 1 body filler system? My supplier said he will give me some to try for free!

[b5blue]

 I found a great price for a gal. of Kirker Brilliant White urethane (activator included.) 73.00+shipping. (A 90's Chrysler paint code.) 
  How many gal. for the whole car?

Believe it or not i tied some NAPA tec one supreme bondo. its a little runny but its all our shop uses now it sands very well its the best bondo ive used to date beating uot all others . thers very very little fine pinholes  .. its worth a try I tried some bondo gene winfield got called( Filler up)  and the holes were more like craters.  trust me with the NAPA tec one.

The Quantum 1 uses a caulk gun with mixing tips....no air mixed in!   

[superbirdtom]

If what you want to do is bury all the old ,,including rust and old paint and crap . then id go with the eastwood stuff.   you can let it sit for quite some time.  and you can always recoat anythig. just go over it with soe 320 on a da  and wipe down with a mild wax and grease  then over reduce some epoxy for your first coat ,and im talking just a fog coat ten follow with two full wet coats , wait 20 minutes for flash time.    

Ive really only used  corlar epoxy from dupont napas epoxy and ppg epoxy.  theirs a lot of shops that use ppg epoxy and topcoat with something else as its very good epoxy.  I reduce out ppg's epoxy 10% so as to not get orangepeel  cause paint goes over it right away.  ppg epoxy will work under any paint system . I like the grey dp-50 LF  it covers very well. you can also tint it ,I just did a yellow mustang and put a little 4% toner in it and it was a yellowish base that covered better.

Ive seen that stuff in a magazine, Id like to try out all new technologies.  but I just use what makes me the most money and is the fastest.    Is it worth gettin?

[b5blue]

  I'm gonna try some and report back. I found for a production shop with tech's well experienced in this, it is most likely too costly. Retail is 20 a cartridge but I found it cheaper so will see. I suck at gauging how much hardener to add and mixing fast so for the many small repairs I have it could be a great help.  There are videos on YouTube from Evercoat on it. One of the advantages of this "temporary paint job" is I'll find what works and what fails. I can go right back in to fix and re-shoot the area.

  Update, Eastwood has their 1 to 1 epoxy primer gallon on sale for 59.00 with free gallon of activator. I think it's re-branded Kirker products they use so I got some to try. @ 2 gallons mixed for about 71 bucks shipped it's worth a shot. Some forums have said the Kirker epoxy primer is good and Harbor Freight HVLP spray gun is actually not a bad working unit so I picked up one of them and a gravity feed gun to try out. As this first shoot will be sanded down and having filler and other repairs done I'm not to worried if the guns suck.     If they do work OK I can use them 1 or 2 times and throw them out they are so cheap.

[hemi-hampton]

YES, The cheap $30 Harbor Freight spray guns work good for primer & sealer. I use them. Primer guns gets trashed pretty quick & I dont like the ideal of trashing a good $300+ Sata Jet, Devilbiss, Binks, awata, ect, ect.  LEON.

Yes, Eastwood (and Summit brand) paints and primers are relabeled Kirker. Pretty decent stuff for the money, I have used the epoxy before and its pretty good.

The cheaper guns are perfect for primers, they lack the finesse of the good guns and that's absolutely perfect for primers!

I'm using a cheap a Central Pneumatic HVLP gravity feed gun purchased at a swap meet for my primer gun. Works just fine, lays it on nice.
I'll save my nice SATA for clear.
