This is an interesting trick.
Seems to me, the goal of the pre-buff solvent is to dissolve a thin
skin of the inner liner, so that we're down to a different layer of
rubber for the patch to adhere to.
What I like about this trick is that it negates the need for the
pre-buff solution, although if the pre-buff solution is Naptha or MEK,
it's easy to come by in the home box stores.
So, the real trick will be to find a substitute for the final inner

They are all different - can;t use one in place of the other, and
foolish to try something not made for the job.
Neaver heard of RTV Silicone?? R for ROOM, T for TEMPERATURE, V for
Why would you? It's only YOUR LIFE riding on that tire, and the lives
of everybody you may hit if the tire blows on the road. DO NOT screw
around with tire , brake, or steering repairs. A criminal negligence
charge will stay with you for a lifetime even if you survive.
That "most critical" fluid has only become anything resembling common
in the last decade or so. It was virtually unheard of when I was
working as a mechanic and fixing tires - and I'd venture to guess
better than 90% of tire repair shops still don't use it - barticularly
with a "mushroom" patch.
This isn't the ladies' knitting group.
Nothing has been patched yet.
This is a *discussion*.
What we're seeking is a second source for the fluids used in tire
repair. If you think that these fluids are *super special*, then
you have a different opinion than I do.
I *assume* (yes, I know) that these three fluids are commonly available.
I'm just trying to find out *what* they are.
You would probably say "just buy the professional stuff" and that *might*
actually be the best answer. But, oftentimes the best answer, for a
homeowner, is to use the same fluid, but packaged for the homeowner.
For example, if the pre-buff fluid is either MEK or Naptha (as has
been opined so far), both are easily available at Lowes.
The sealer is the trickier fluid to figure out what it is, since
that is the fluid that protects the inner seal.
This is interesting. You have far more experience than I do, so I
greatly appreciate your advice. Today I stopped off at Costco to
see what they use, and they showed me a can of their stuff, which
they use as part of the final repair. But I don't know what other
The trick now is to figure out *what* that tar-like substance is
made up of, to see if we can find a second source in the home box
I think a lot of these "proper ways" are fine but are often simply
driven by lawsuits. Some gas station repaired a flat tire, the guy
then has an accident and blames the repair and gets paid "experts" to
testify it was all because of that improperly done repair. No
evidence that a "proper repair" would have changed anything of course.
The same reason some tire places insist the new tires HAVE to go on
the rear of the car leaving you with half worn out front tires on your
FWD car at the start of snow season.

Certainly millions of tires have been plugged from the outside.
I even saw plenty of videos on how to repair slashed sidewalls.
But, still, this is a repair and tech group.
We can fix things any way we want; but we should, at the very least,
*know* how to do it right.
Depends on the research. They have a financial interest in anything
that results in them selling more tires in total or more tires then
the competition. Competing is hard, getting the gvt to mandate
something stupid so you can make more money just takes a few lobbyists
and greasing some palms.
True. This is not mandated by the gov't. However the manufacturers have
researched this extensively because front wheel or 4 wheel drive is now the
norm. Some where there has to be trust, because why not just slap undersize
tires on, run oil to 25k, one doesn't need that piece of plastic there, no
seat belts, etc. You make your choices then live with them.

I know this was directed at someone else, but, let's remind ourselves
this isn't the ladies' knitting group.
We're here to learn how to repair things, and, in this case, what
we want to learn is the proper way for a homeowner to repair a
car tire that has a puncture wound.
So far, we have learned a *lot* (at least "I" have), as I have
read the wrong way and the right way to repair the tires.
The only thing I don't have are the 5 tools and the 3 fluids, so,
my quest right now is simply to find homeowner-style alternatives.
One could rightly say just buy the right tools & fluids, but,
you have to realize that we're only going to repair one tire
every few years, so, we really need to be smarter than that.
Sure, it's *easy* to buy exactly the professional tools, but, if
we're smart, we can buy the fluids and tools and be able to use
them for other things.
For example, of the three fluids, we seem to know at this point:
1. Pre-buff solvent <= seems to either be Naptha or MEK
2. Vulcanizing cement <= easy to come by almost anywhere
3. Inner liner sealer <= this we don't know what it's made of yet
Of the 5 tools, we can probably make use of existing tools:
a. Carbide reamer
b. Pre-buff half-moon scraper
c. Half-round buffing wheel
d. Stitcher wheel
If you know of alternative sources in the home box office for
any of these tools and fluids, that's the stage I'm currently
Whatever you impart will benefit all of us, because I would expect
anyone at home who can mount and dismount and balance a tire to
be able to also patch the repair from the inside.
Another path would be to approach this from the side of
social engineering. Rather than a gallon of each for one
tire patch, you might cultivate a local tire shop (or
tractor supply or such), do your path with him at the end of
the day using his tools and supplies/materials and leave a
crisp $50. If your goal is education, start with someone
who knows the area and is nearby for advice as you go along.
That would work, but, I'm gonna take the "homeowner" route.
That is, I know how badly most homeowners do it (they buy the
$5 string-plug kit, shove the thing in with glue, twist,
pull out, and cut.
So, "my" repair can't be as bad as that typical homeowner
repair, no matter *what* I do!
I already bought a few tools, most important of which is the
rasp and the stitcher, so, I'm fine with respect to tools (the
scraper and buffer are pretty much finesse - remember - compared
to the "typical" homeowner job).
The one tool I pine for is the carbide reamer. I think what
I will do is look for a carbide reamer in the box stores. I
might even break the handle off of the hand reamers, and put
that "bit" into the drill at 500 RPM to see if that works.
Once I have the carbide reamer, that's all I really need.
So, here's the shortcut to a "decent" repair:
1. buff the inside
2. ream with a carbide bit
3. glue in the patchplug
The one solution that really has no decent alternative yet
is the final covering of the rubberized carbon-black naptha.
Snipped because I'm tired of seeing the same reply to posts. It was directe
at you. As others have said there are some things others should do. If you
REALLY wanted to know how to do it you would have DAGS. Education is not
free. The uneducated have to pay the price. You are paying nothing but
replying with snarky knitting group answers. Grow up. The world doesn't
exist just for you. You are on the same plane as Stumped.

This is wrong. Dead wrong. But you're entitled to your opinion.
If you don't know how to do it, you don't really need to respond anyway.
I'll learn from the guys who *do* know how to do the job right anyway.
If you think for a split second that the guy who repairs your tires
gives a hoot about your safety, you're dead wrong.
They're just trying to get "stuff" through their shop.
That's it. To them, you're just another 'job'.
The proof is that *every* time I watch them, I see them make mistake

The ancient adage still holds, despite the fact you seem to think
it doesn't hold true.
If you want the job done right - do it yourself.
Did you ever have tires mounted or an alignment and you watched the
"professional" do the job all wrong?
So, at the very least, we all should know how this plugpatch job is
done correctly. If for no other reason, than to be intelligent when
we watch someone else do the repair, so that we know if *they* did
the job right.
At the moment, I think we all know *exactly* how to do the repair
properly (following the well-established RMA procedures).
We also know exactly what 5 tools and 3 chemicals to use.
The *only* thing left is to see if we can intelligently second source
any of the 5 tools and 3 chemicals so that we can use them for other
purposes around the home and car.

Clare thinks he's the only one who knows anything or is entitled to an

base or different then he (or she) believes, his (or her) panties get
