Chris, if you replace the screw with a cork I think you will find that it won't seal as well as the screw. As for pouring left over DN back into can you will contaminate what is in can. Since what you had out has begun to set while exposed to air that reaction will continue in the can and you will probably loose entire contents.
Mark, the syringe idea sounds good. I would be leary of it though. I don't think the syringe will seal as well as the screw, and you would have to turn can on it's side while dispensing from the syringe. As the hole for tip or syringe will be larger than for the screw a lot of air can enter while you dispense. The syringes for Flexcoat work very well since no chemical action occurs until both parts are put together so it makes no difference if air gets into the bottles.
Just my two cents.

I definitely think that trying the syringes is a good idea. You could use just a small amount to test it out. If it doesn't work, no big loss. If it does work then you have a great idea!

Tap a keg, pump, or other, the important thing is to manage the headspace in your container of leftovers. The gas that fills that void should be dry, oxygen free, and heavy. I (and others in the woodworking community) do NOT recommend using propane, butane or any other chemically reactive gases in your finish. We use only ultra pure Argon for our product. Argon is a small percentage of the air we breathe, but it is also an inert, noble gas that's heavy and totally dry. It has no reactions with any chemicals or elements.
Bloxygen is only about 12 cents per use, it's simple and it works well.
Just trying to help.

I use both DN and D2T. Both have thair place depending on what you are doing.
I had never been so frustrated in my life with a problem like the storage of DN.
I tried everything possible for years including Bloxygen and wasted I don't know how much money on DN.
The method described by La Pama on using a self tapping screw and keeping the can on it's side is the only thing you should ever fool areounfd with It works and it works to kleep any moisture cured coating for as long as you want to keep it.
Thanks for the tip and dont waste your time or money with any other method.

I have used syringes and they do work. The only problem I ran into was that the rubber seal over time in the syringe begins to get damaged.
What kind of screw are you using for the "self tapping" tap the keg method?

Just a stainless Steel 3/4" self tapping (pointed) screw.
The DN will form a seal around the screw after I punch it with an ice pick and screw in the screw.
The original instructions say to store the can on it's side with the screw up.
I do that also.
Like everyone in the comments, I ran into some problem with ever other method I tried except this one.
