Yes, the outside of the jar. That is why we use filters for our sterile media 
Well yeah, . but even when the jar is knocked up, there are bound to be a very small amount of contams that get in. The mycelium out numbers and out competes the competitors and the jar is happy.... Well in most people's jars.

If there are any contams present that the mycellium must "fight" you already lost the battle.
Inoculating should not introduce any kind of contamination, if it does you are doing something wrong.
This is not a race against contams.....

I was under the impression that when using multispore from a print, there is a good chance some sort of contam could get in. But generally an irrelevant amount. Or is that wrong?

Put something heavy on the lid to hold it down.
It's the same method for cooling big pots of soups or sauces before putting them in the fridge to chill.
Of course the reason I ask is if someone else has already thought of this and tried it and ended up getting contaminants due to this then obviously it wouldn't be worth wasting the time to even try.
Horrible idea.
Allow the substrates to cool slowly to avoid damaging the filters by the sudden rush of air and/or loss of pressure. It's sterile inside the pressure cooker and jars until you open them. Allow to cool slowly for 12 hours or so until you can handle the jars without protection for your hands from the heat.
Remember, we're sterilizing, not cooking a soup. RR

Not trying to be contrary here but taxes don't pay for the postal service. All revenue for the post office is generated through stamps/shipping costs.
Edit: I read through this post too quickly and thought the discussion was on pasteurizing, not sterilizing. It's still very early here. COFFEE.

Cool, I haven't been able to find micropore tape thus far but I found breathable paper tape that was in the pharm section. I just put a piece over each noc point and put another over it after I injected.
I hope that wasn't a bad idea since the second piece of tape obviously wasn't sterilized.
I also don't have an FH but intend on trying to build on in the distant future, until then I do need to make a glovebox.
I know most people are probably gonna slap their foreheads but I opted instead to turn the a/c off, clean my entire work area with bleach water solution, and just do them inside of a sterilite container that I wiped down with bleach solution.
I know it's not perfect but until I build a GB it's the best I got. Plus we keep our house pretty clean.
In retrospect, I could prob just cut holes in the side of that bitch so I can work with the lid on, I mean it's not a true GB but until I find tyvek sleeves and buy the silicone and pvc its a hell of a lot better than working in basically open air.
