Like I said before "don't screw around with tire repairs" "It's only YOUR LIFE at stake." Don't prove yourself stupid.

This isn't the ladies' knitting group.
If we can't wind our own garage door springs, install our own struts, and patch our own tires, we shouldn't be on this newsgroup.
Nobody is born knowing this stuff, so, all I ask is that those of you who know what you're doing, just help out the rest of us to learn.
I already know *exactly* how to perform a proper repair. I know the tools. I know the fluids.
Now I'm thinking the fluids because most of these fluids are not *special* to tires is my thinking.
Maybe I'm wrong. But I doubt it.
For example, if the prebuff is Naptha, that's *easy* to come by. The one fluid I don't know the composition of is the final sealer.
Any idea what that final sealer is made out of?

Mineral spirits and MEK are totally different materials. Mineral spirits is closer to the right product but can have all kinds of fraction in it that could inhibit proper vilcanization.. White gas (coleman camp gas) is about as close to the "real thing" as he is going to find at a big box store like Home Despot. - much better to just get the right stuff

I think naptha is fine.
Lowes has it by the gallon.
What I'm trying to source now is that final goopy tar sealant.
Any ideas what it's made up of?

This isn't the ladies' knitting group. This is a repair and tech group.
If we don't know the exact chemicals used in the three fluids, then we have no business being *on* this newsgroup.
Likewise, if we don't know the purpose of the five tools used in a decent patch repair, then we can't call ourselves all that knowledgeable.
None of us are born with this knowledge, but, those of you with experience can help impart your knowledge on the rest of us.

I would use what the patch company recommends. Tech's "Rub=O-Matic" rubber cleaner has no MEK in it. it is basically a light naptha (pure petroleum product)
Rema uses a water based pummice product to buff the rubber liner for repair. Their flamable pre-buff is almost pure N-Heptane. Their non flamable pre-buff is Triclorethelene
The "glue" is also specific to the patch product being used. -I would not mix one company's glue with another companies specialized patch products.

Naptha is easy to come by, so, that would be good news.

Heptane should also be easy to come by, so that would be good news.

Interestingly, one of the videos I posted said to not coat the stem of the patchplug with the glue. The other one didn't mention whether or not the stem (near the head of the patchplug) should be coated.
Do you lean toward putting the cement on the stem of the patchplug?

And that is what the "scraping" is for - to expose raw clean surface for gluing..
The old trick of applying glue, lighting it with a match, then scraping off the remains before applying more glue and the patch did the same thing.

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 liner sealer.

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 VULCANIZING

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 shops use.
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 stores.

Oh, more memories. Monkey Grip - I can still visualize the can and lighting the glue....
Let's take this tread to re-vulcanized condoms. Maybe more posts.

Same here. I've done 4 or 5 that way. Kits cost $3-10. They didn't come with a rasp when I was buying them.

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.

So I guess the research the tire co's means nothing to you.

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 d 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.
