I have a 95 wagon and at some point had a large chip of skim coating come off I guess what be the c-pillar. Talked to some body who said he used to do paint and body and said the mid 90s accords were all like that along the door pillars because of factory warpage. The car doesn't have any damage between the rear door glass and rear wagon glass. Is he pulling my leg or did most cars have a skim coating there

If you have a second wagon use a fridge magnet and see if there is filler where your other wagon has the filler.
Most cars have a bit of seam or joint filler in certain areas, but is usually is not too thick and usually does not fall off. It's not typical bondo.

I will check as I do have a 94 wagon. It didn't really fall it's more like it cracked and got water under it. It came off as a triangular shaped chip about 1/16" thick

Sorry if the image is too big

That is bondo. You can see the grinder marks on the rusted metal. That is not factory. Even when metal is not correctly stamped, OEMs tend to leave it be. Plenty of incorrect stamped panels on mass produced cars that fit but have a wow, pinch, crease or other stamping defect. This is a repair.
Granted the wagons may have not been as mass produced as the coupe and sedans but I cannot see Honda wasting time, with bondo, to fix this flub, especially putting bondo on an edge. That is a failure waiting to happen.

Would it be in my best interest to pull it up as far as I can go, treat the rust and reseal then paint?

If the filler is lifting due to the rust then yes.
Bondo is a bitch in that it is a sponge, as soon as it is fully hardened it needs to be sealed, othwerwise it will trap water and create a larger(rust) problem.

Remove all the loose and lifting bits. Then sand it down to clean up the metal and if you find filler that is properly bonded to the metal you can sometimes get away with leaving it attached and just cleaning up the failed sections. But again bondo will attract and hold in moisture, nearby sections may not be immune. You can often see how far the moisture has invaded by staining of the bondo. But this is your call. You can remove it all, remove all that you think is bad, or be lazy and just knock off the loose stuff grind>seal>primer>paint
