I am NOT saying one does not need to use anything with caution. I am NOT saying that the post is wrong. What I am saying the view is too subjective and there is no statistic to back it up. I do not smoke, but it does not imply that I will not get cancer. With the same token, I do not put sealant into my A/C, it does not mean that my A/C will live a long and happy life.

I think over 95% of this forum would agree with the geometry teacher. The stuff is crap. Percentiles and statistics should be thanking Larry for the informative post.

I can just imagine joe schmo putting can after can of that stuff into his car, giving up, then going to the AC shop. I bet that's what happened with that goobered up compressor.

It might not be evidenced in the video, but there have been MANY systems destroyed by sealants.

Most people who resort to any "fix in a can" are usually in the "I have nothing to lose" camp - in other words they have a leak and figure it is worth a shot and don't realize it can damage the system. Either that or they are used car dealers just trying to get a car off of the lot.

In fact, if they suffered a compressor failure after a few months they would simply figure it was unrelated and be happy the $10 fix bought them a few months of cool air. There's no way you can prove the stuff caused the failure because most of the time it is being used in such an old system they can claim it was at the end of its life anyway and the failure wasn't caused by their product.

Marty,

You bring up some very good and logical points, but don't ever underestimate or try to outguess the public.

A guy I know who has an auto a/c shop said that you would be surprised at how many relatively new vehicles come into his shop that have what would have been minor fixes for him, but since he detected the sealant he couldn't do anything for them and serious damage had already occurred.

A skin flint is a skin flint. I should know, I am one. I've done my share of making things worse in an effort to save a relatively small amount of money. The only thing between me and having my a/c system destroyed by this junk is the fact that I am aware of it. With this post I'm trying to pass that awareness along.

I just got back from the auto parts store; I took a look at the display out front with all the R-134a stuff in it. Nearly every Interdynamics brand can had leak sealer in it, whether it was "high mileage", the regular stuff, or the small oil charge can. The only thing without sealant that I could see were the few DuPont brand cans off to the side. Still makes me think how many DIY types unknowingly introduce sealant into an otherwise repairable A/C system because from what I saw it was hard to swing a dead cat in the parts store without hitting a can of R-134a with sealant in it. In fact, I remember being told at one time that the cans with the sealant were all that the parts store had available; needless to say I bought no refrigerant there. Probably where the fairly new vehicles are showing up at the A/C shops with sealant in them. I'm sure most of the people who put the sealant in their system would not have done so if they knew about the serious drawbacks that they obviously have. That only leaves the guy at the plastic flag car lot and the down on his luck car owner about the only ones who would roll the dice with the sealant, at least in my own estimation.

We were at Walmart, while my wife was over in the Yardage dept., we walked over to the Auto Dept. he looked at all the 134a on the shelves, and remarked it was junk with the sealant. also had some comments about the connections and gauges these cans come with being crapy.

Sealants can void warranty
Both professional technicians and vehicle owners are routinely using sealants in mobile A/C systems. Most of these A/C sealants react with moisture and air to create a seal. They are carried through the system by the refrigerant oil and escape through the hole in the system and solidify to form a seal. These sealants can enter A/C components and A/C service equipment and cause damage by solidifying in the solenoids and tubing. In many cases, manufacturers of A/C components and recovery equipment are voiding warranties when damage has been caused by A/C sealant.

Report on A/C sealant effectiveness

You will be the judge on sealant but if an A/C shop buys the Neutronic's detection system and do NOT touch/repair any system with sealant in there then they will go BUST in no time as according to Neutronic, it is widely used.

Go bust by turning down a job that pays $100 but trashes a $4000 machine?

^^^^^^^^^^^^^^^^^^^^^ Here's a logical thinker for you ^^^^^^^^^^^^^

There is no logical thinker. Just purists.

One promotional video with self vested interest and all sealant are condemned. I do not use it myself knowingly but I would not condemn it as junk without any proof.

It doesn't hurt or take much time to label it if you do use it.

This allows the mechanic about to work on it decide for themselves what they think about it and if they want to chance working on it.

Common courtesy in my opinion is the root of this thread rather than product review.

Can I ask you a question? Have you ever run a business, or any part of a business where profit and loss decisions must be made? It would not surprise me if your answer is no. ANYONE with any knowledge of profit and loss can EASILY see the problem in risking destruction of a multi thousand dollar machine for a $100 job.

If you still believe that this is all a big bunch of hype, I would invite you to stop by your local auto a/c shop and ask them how many systems use this stuff, how many have been ruined by it and if they are willing to risk their recovery equipment without checking for sealant first.

For the life of me I can't imagine why anyone could be so bull headed about something that is experienced and observed in every auto a/c shop in the country on a regular basis.

Unbelievable!
