I stripped all my panels a while ago and gave them a decent coat of red oxide, ive just started sorting some of the dents and welds with filler and don't want it all to go rusty again, bearing in mind this car lives outside under a car cover and some tarps, should i paint over with a Barcoat type sealer, 2k primer or epoxy sealer (are they one and the same?) Which will give me a weatherproof coating and provide a good base for when i eventually get the car painted?

no primer is designed to be long term weatherproof
Mostly epoxies have water resistance capabilities,
Regular 2K primer is porous
barcoat is an isolator and its waterbased so probably will fail quickly in weather
Best course is to store them indoors really

they're attached to the car so cant keep them indoors, what about a coat of isolator with epoxy primer over the top?

Why not just paint it? Coat of normal primer, then a quick messy coat of cheep flat paint. It'd likely be cheaper than epoxy primer or a barcoat.

i was told epoxy is mega hard when you do come to try and flat it back etc. think i'd use etch primer, then 2K primer and a cheap top coat as short term protection until you paint it proper

I just bought a miss-mixed small tin of cellulose and threw that over the Galant's Primer over the winter. Has had zero rust damage apart from a couple of very small areas which I don't think I covered well enough (they were only dusted with hindsight)

Etch prime it then 2k it, then chuck a guide coat over it so when you flat it back your inperfections will show up this will also add a small amount of protection. If you properly put a coat of paint on it you run the risk of micro blistering if you cover it up! the paint needs to breathe for as long as possible when fresh, as does primer, so i think a guide coat then grab a rag and some petroleum jelly and smear it all over, it contains no silicones and washes off easy with panel wipe  |

2k epoxy is waterproof (but check the data sheet for the chosen paint). The stuff I'm using under my car is good for "below the waterline". Wouldn't want epoxy outdoors for too long, it isnt UV-stable, though it takes a while to start chalking up. Also you run the risk of other contamination although it could be well-cleaned and sanded back. Make sure no silicon ges anywhere near..
It's meant to go onto bare metal. Putting it on top of red oxide may work, but the oxide might react.
Epoxy is both a primer and a sealer.
Being 2k, make sure of all the H&S stuff of course. Could be rollered on. won't be pretty, lots of flatting later, but guys do it.
fwiw I wouldn't use red oxide on bodywork, but I did slap some on some wheels and left them outdoors uncovered for 7-8 months, over winter, etc. Not a trace of rust came through.
If it were mine I guess I'd epoxy onto bare metal after doing filler etc, store them off the ground, all covered to keep light out (not individually wrapped that is).

ok, I thought you meant the panels were loose.
I'd roughly paint them in any old gloss paint over the primer. I've even used lacquer on primer to keep the water off it on cars which were "pending" a proper paint job
