i like the Permatex motoseal also I've never had the grey ultra grey never even get tacky after that long ever I've probably used 1000s of tubes of it in 30 years in the automotive repair industry, the motoseal is more fuel proof and I use it often in 2 stroke engine cases

Yesterday, one of my tech assembled a complex engine using Permatex product that should fully cure within 24 hrs.
He came back to work today, and after 18 hrs sealant is still wet, not even tacky.
We use this company products for decades and never had a single problem with sealing/tacking or anything.
He was totally p'od, as this particular job took him 6 hrs, so we sent him home to relax.

Meantime, I did a test of the same products from four different tubes:
* an old/opened good sealant & unopened, both grey tubes, R-side pics
* the sealant he used & unopened, both black tubes, L-side pics
After couple of hrs, the grey tube sealant was curing satisfactory, unlike the black tube sealant was still wet.
The black tube sealant he used to seal his engine parts still wet after 34 hrs.

Both product have the identical OEM part numbers and bar codes, however the "serial or production numbers" at tubes bottom are different, but I do not think it matters. Both sealant substance is of the identical grey colour.
At this moment there is no more info/Saturday, and we will resume our inquiry on Monday.
I am thinking of some technical glitch, like missing hardener/curing ingredient during production process...counterfeit....or ?????
So if you doing a complex or big jobs with this product, do yourself a tacky test prior to avoid doing it twice and wasting(?) your time.
Hope to update this thread next week.
If you have any info/thoughts, share please.

After four weeks there is no update at all, as the Permatex head office has never responded to our email

Totally unacceptable. The corporation needs to held accountable for wasting consumer's time with a substandard product release.

Read the text you're showing (backside), and even so I do realize that the specs say the product is good for "minus 54C to 250" or sth, I wonder if the bad tubes had seen freezing temps for a longer period of time - not even -54 but just -5 or -10C - before use. Not every product which can stand low temperatures when cured, can stand sub-freezing temps in storage (example ultra-rapid glue). But admitted, this is just a wild guess.

It seems overseas scoundrels are counterfeiting new things every day - not sure if this is one of them, but somehow I wouldn't be surprised. That being said, assuming this is NOT counterfeit nor how Permatex intends the product to perform, it is likely a bad batch.

Some years back, a buddy finished college with a couple scientific degrees, but couldn't land a job in his area of interest, so he took an interim job working nights at a big name detergent factory. His job was QA for the huge vats of the various detergent and surfactant products the plant was making at the time, running 24hrs a day. Essentially, he was, without being given the title of "manager," responsible for how all the night shift guys did their jobs adding ingredients, in specific quantities, at specific times, etc. You get the idea. For context, the guys working nights were not the pick of the crop; many were lucky to have finished high school and for some, their citizenship status was in question as well as their ability to read/write English. There were the stories about OTJ alcohol consumption, having to somehow hose-out a factory of a six foot tall wall of suds before the morning people arrived, vats of product having to be flushed down the sewer due to over-addition of ingredients, etc. My buddy didn't stay for very long.

The takeaway was that the daytime crowd of managers, engineers, chemists, etc. may have been top-notch. In their case, the product quality was only as good as the night shift was sober/not stoned/felt like paying attention/actually showed-up to work. Who is to say there wasn't a mistake made at the factory for this product?

... could also just as easily been an educated college graduate of systems software who committed some bad firmware that caused the automated system to mix incorrect proportions of the ingredients, or similarly some other part of the process provisioning.

Also could have been a bad sensor reading in the automation equipment that was ignored by a human.

As another Forum member mentioned, maybe the batch was left in freezing temperatures in a truck in transit to a warehouse or final destination.
