i'm thinking of buying a 100 box of the patches only and would like to know if they have a shelf
life, properly stored of course.

I got a box of 100 about 5 years ago. I take no special care of them re storage. So far, they have
not shown any obvious signs of degradation.

The patches seem to last for years. It's the GLUE that dries up, even if the tube is never
punctured. Takes a few years, but it will dry up eventually....

My only negative experience to buying patches in bulk is that after a while it seems the
plastic film becomes almost impossible to remove after applying the patch. It this doesn't
bother you, go ahead.

How do you try to remove the film? I once had problems because I was trying to peel it from the
edge. I finally noticed the slice across the
middle. Stretch the glued-on patch across the slice, and the film splits. Once it splits, it's
pretty easy to get it off.

Where'd you find them? I've been looking around, but haven't had any luck.

Also, what do you use as glue? Is it just rubber cement? (All the tubes that come with patch kits
say "Vulcanizing solution" or some such)

I use rubber cement. I have a small can of it that I got at the local Office Depot. It's lasted a
couple of years so far.

I bought mine from Loose Screws Bicycle Small Parts,

A local bike shop sells Rema cement separately from the patch kits, in a somewhat larger tube.
Monkey Grip rubber cement from an auto parts store did not work well with the Rema patches.

I never remove the "films". Why bother?

concur. what i noticed is that w/ the film the patch is less likely to stick to the tire. (yes, i
use talc. and yes, i'm confident that it's the patch and not the surrounding glue that's sticking
to the tire.)

You must have wondered why the manufacturer bothered to make removal of the cellophane easier with a
central split. The intent was to help in removing it before inflating the tire. If it is not
removed, the tube will tend to not expand with the tube even as poorly as it does without the
cellophane. This cover, like the foil on the adhesion side is there to prevent the patch from drying
out and becoming brittle. Being inelastic, when not removed, it prevents the patch from expanding
with inflation to seat in the larger cross section of the tire casing. This can help in dislodging a
patch if the tube is used right after patching.

Why do you use talc?

How is the film attached to the patch? Are the expansion forces of the tube less than the adhesion
between the film and the patch?

What bothers me is the edge of the patch is feathered and the film often starts pulling up the patch
here when it is pulled away.

I find that by the time that I need to put the next patch on and look at the last one, the plastic's
essentially shreadded.

When I do remove it, I pull one corner up slightly and then separate it from the patch with my
fingernail. I continue to use my fingernail to hold the edge of the patch down, and press it firmly
again when the plastic film's off. If the patch comes even with the above, you didn't let the glue
dry enough before putting the patch on 🙂.

That takes a little time and goes along with the test I suggest for people to see how severely a
bias ply bicycle tire massages a patch that has just been installed. Laying a business card between
tire and tube, it will be turned to confetti in less than 100 miles. However, the stretch effect I
mentioned is more immediate, before the cellophane is torn up.

The cellophane has a practically invisible split across the center of the patch. By stretching the
patch, this split will break and the foil can be peeled away from the center to the outside. I often
get the impression that people who do not remove the cellophane are not aware of this intended
removal method.

Stretch effect? If a repair patch is applied to a tube which has been inflated to an operating
diameter or larger (usually the case), then the stretch effect is between the ears rather than on
the tube after installation and inflation.

Patching over a blowing leak is not a reasonable method for applying a patch. Besides, when
deflating the tube for installation, the patch will buckle into a dome, under which the tube pulls
away. I suspect this is one of those specious offerings from a disgruntled reader.

It's been forever since I've bought a patch kit. I use old innertubes for making patches because
they are a dime a dozen and I can cut a patch to any size that I need from them. I use some common
rubber cement to make it stick. A few times in a pinch I've used RTV Silicon sealant and even Goop
as glue. Never had one fail. The best patches I've used are some old Camel hot patches I have left
over from my father when he worked for a service station. Patches are at least as old as me but
still work like a charm. The rubber is still good and they flare up like new. If you can find new
ones available I'd recommend them.

I tried that but I didn't have any luck using pieces of innertube. Additionally I like the feathered
edges of patches.
