Carrying rubber cement
 

Too many times I go to patch a tube while out on the road and find my little tube of glue all dried up. Seems like if a tube of glue gets hot, which it will if your seatbag is in the sun, the tube will dry up. I've even had ones that were never opened dry up. Then, if you don't have a replacement innertube you are SOL.
At home I have a screw top can that holds about 8 fluid ounces of glue. I was wondering if I couldn't put some of that in a small jar and keep it in my sestbag.
As it is now, I buy those little patch kits and the glue dries up or goes bad before i use up all the patches. I have several Glueless patch kits laying around the place. I hate buying a patch kit if all I need is the glue.
Too bad they don't package glue in little single use "ketchup packets".
Any reason you can't put glue in a little glass bottle and carry it in your seatbag?

I get the glue from Walmart $1.68 in a patch kit.
Also found same at the grocery store.

I carry three tubes on the bike.
Patch at home.

the tube of glue is not really glue, it is rubber vulcanizing fluid. it actually 'melts' the rubber a bit to allow the patch to adhere to the tube.

I am with 10 wheels I always carry a spare tube or two and patch when I get home. I do carry a patch kit too. buy the park glueless patches.

I've got the vulcanizing fluid. Just wondering if there is a handy way to carry 1/4 oz. or so. I always carry a tube, but if it's a nice day and an easy fix I will patch the tube on the spot.

You could, sure. Cold vulcanizing fluid goes bad for two reasons. One is that the solvent that keeps it spreadable evaporates. Second is that it vulcanizes itself into a solid mass. As you note, heat is a big cause of both of those things. I don't know how you plan on getting the cement from your little glass bottle to the tube in a suitably thin layer, without getting it contaminated or your hands filthy. And it'll dry out in your glass jar, too.

Perhaps a nail polish bottle?

It is intended for volatile fluid and has a suitable applicator.

Now which one is the wife least likely to miss?

Super glue works just fine in a pinch - I have even used super glue on a piece of thick plastic for a patch on a motorcycle - It held up for months and then I replaced the tube for fear of failure - Just throw a tube of super glue in with your rubber cement as a back up - Super glue can also be used for various other first aid treatments on both you and your bike...

I carry 2 tubes of glue: one that might have been previously opened and one never used before as a backup.

I buy a fresh patch kit each spring and put the fresh tube of glue in my saddle bag.

I carry a spare tube (a second spare on longer rides) so rarely patch on the road (only when number of flates exceeds number of tubes which is rare). I carry a new patch kit with unopened tube of glue. If I use it, the glue goes into my tool box and is used for patching at home and a new, unopened tube takes its place. Never had an unopened one dry up.

I bought the larger size tube of glue, to carry along with my regular patch kit tube, and a spare inner tube. And some glue-less patches that I haven't tried yet. I figure if I'm going to go to the trouble of changing the tube anyway, I may as well have a go at patching it out on the road. Easier to find the little piece of wire in the tire, as well.
