Is there any way to keep the small tubes of sealant from drying/hardening at screw cap? Even the small tubes are so expensive and they harden quickly.

I have a system:

  1. carefully clean the threads
  2. replace the cap
  3. place tube in Ziploc bag
  4. roll air out of bag and seal
  5. place in fridge
  6. wait
  7. remove from fridge
  8. dispose of responsibly

To be sure it is a stupid system, but it's mine and I love it uncritically.

Truly the voice and wisdom of experience.

Leave them on the shelf at the marine store. Failing that, remember that most are cured or catalyzed by moisture. Marine air is full of moisture. Before screwing on the cap very quickly squeeze out a bit, wipe off clean, and quickly seal. The less catalyst trapped inside the better. Then follow the above rules from @weightless.

I just use duct tape. Or electrical tape. And a long screw to plug the end. It's easier to remove the hardened plug of caulking that forms around the screw if you just pull it straight out.

I typically get many months out of Sika 291 or Lifecaulk.  3M products - not so much.

Great for parties. Tell your friend that you can't give your cat birth control pills but you have these. Bit of a struggle to get them on...

I showed my daughter a video of "Ozzy the desk weasel". Its adorable but does remind me of our last cat who would randomly attack you and then run away.

She starts googling " do weasels make good pets ? "

The first answer is NO!  Thank God...

My middle daughter was lobbying for a ferret for a long time. We "compromised" on a mouse...Now she's Guinea Pig curious.

One thing you can try is to take a small square of plastic sheet (cut from a poly bag or whatever), fold it over the top, then screw the cap down over that. Sometimes works. But I usually use the Weightless method.

For some things, I get away with shoving a large nail in the open end.  Hopefully so that the head doesn't interfere with the cap.  Pull out the nail to open a passage to free goop.  Most of the marine sealants, I end up cutting off the spout to get the second use.  Then cutting off a bottom corner for the third use. Then throwing the rest away.  

 
Squeezing out a little, tightly capping it with electrical tape then replacing the cap if you can wedge it on may help.  Although as the owner of an aging 35 foot keelboat that we race pretty hard, hustling to save $12 three times a season seems like maybe my rubric for evaluating cost/benefits is out of whack somewhere.  There might be other ways to save $36.

Put it in a big freezer ziploc or wrap in Saran - keeps the smell transfer right down.

Inhibiting cure of various polymers is a known property of various materials and chemicals. Might be fun to try some.

Never leave the cap off fir more than a few seconds.
On cartridges, rubber band  a few layers of plastic bag over the tip. Mdkevtge bag big enough to hold about a teaspoon of caulk. 
Fill the bag with caulk. For the next few days you will be able to Rio off that home made cap and use the rest of the caulk. 
when the usual exit hole becomes clogged with cured material, use a nail to  poke a hole just behind the cap and dispense through that hole. 
 

if you aren’t going to use the caulk soon, give it away . Lots of folks have dropped off half used new tubes at my shop and I have been happy, if I have had one at the right time,  to hand them an opened partly used tube So they can go install a cleat. 
 

“Can I give you $20 for the last few inches of that tube of 5200?”

When  the nearest stocking store is twenty miles away and traffic is at a standstill , that $20 is money well spent
