Filler over epoxy or bare metal

Hello all,
I have a 1966 Cadillac Deville that is currently stripped to bare metal and covered in Krylon (for temporary protection / on a time limit ). I have moderate body work to complete such as rust,dents, shaving and filling of molding holes.
My question is:
Am I better of stripping the krylon and epoxy priming before repairs OR keeping it in krylon, making the needed repairs, then striping the rest of the krylon and epoxy priming.
I am using SPI epoxy primer.

I'm thinking of keep it in krylon, sand to bare metal to make repairs and then strip the rest of panel to bare metal and epoxy prime just that panel. When all panels are repaired scuff the entire car down and re-epoxy prime then follow with 2k primer.

Any suggestions are greatly appreciated.
Just need to know if I'm still sane or high on paint fumes.

Thanks in advance.

I am sure that someone else will tell you how wrong I am,but IMO....I would strip one whole panel,epoxy prime it.Then do what repairs are needed.When you finish with that panel,2k it,and move on to the next one......like I said....that is just my lowly opinion

Thanks evilone
My thoughts were along the same lines. The only problem I have is that I'm only working on it 3 hours a day and the if I epoxy prime it before repairs I will be sanding most of it back off to do the repairs.

DA the car back down, get all the rust out, epoxy the car with 2 good coats.. Let set overnight and then begin your bodywork.. When finished with bodywork set it in 2k, guide coat guide coat guide coat, block out with HARD block and if it is ok, base.. let set overnight, then clear the next day..

You will love the spi products...

If you're doing it one panel at a time, I'd just sand the krylon off that panel then do your welding and hammer work then apply two coats of epoxy. The next day you can do any filler work directly over the epoxy then either apply more epoxy or go directly to a primer surfacer. If you're working on one panel at a time it should be easy to fight off flash rust while the panel is in bare metal. Unless you're driving this car?

Thanks all.
So the plan is:
strip to metal.
weld holes and shave
epoxy prime
filler work
epoxy prime and 2k

Good plan, you won't be dissapointed, I've been doing it that way for about 15 years now and the work really holds up well.

Sounds good but I wanted to comment on something said earlier. I think it should be a "TIP of the day post".

I am like you. Just an enthusiast and not professional. I dont skimp on tools or materials as I pretty much have the attitude that I dont care what it cost. If its a matter of doing it right, and I dont have the money, it will just take longer.

Anyway I doubt anyone will argue that materials are expensive and we all hate wasting them. The cost of tape, sandpaper, paint, primers, thinners, etc is astronomical.

When you work on one area at a time regardless if its primer or bondo or even paint it takes about 50% more material to do the job. I mix up enough material to spray a fender. Its never exact. I am not one for loading up materials so instead of an extra coat, I dump it out. Pouring a 1/8 cup (quart) or worse of epoxy out is not a good feeling.

So have work lined up like small pieces. Cowl panels, header panels, trunk, etc. So if you are shooting along and end up with a 1/4 cup of epoxy its better to have something small ready to shoot the dumping out your cup.

Your plan sounds very good to me. Better to work on the car as a whole because it will cost you less. I can be more productive doing one thing at a time until its finished but it sure is more expensive that way.
