Q: What types of jobs/repairs did you use this product for?
A: I put the Bar’s Leak HJ-12 into three different problematic jacks. The first was our transmission jack — this one liked to mark it’s territory every time it was used. The transmission jack no longer does this. The second jack was a very, very, very old 50 ton heavy truck jack that just plain leaks all the time. The HJ-12 did not completely cure this one, it did stop the perpetual leak though. Now this jack only leaks when pumping. That is a better result than expected, as I said this is a very old jack that honestly needs a rebuilt or to be replaced. The last jack I used it in had a stuttering problem, both up and down as it were. The Bar’s Leak has cured it’s stutters, sticky pump pistons, so I am quite pleased with the HJ-12.
Q: How did the product function as far as saving you time?
A: This product really isn’t designed as a time saving tool. On the other hand using it should stop having to constantly check and fill your jacks. That in itself could save you quite a bit of time.
Q: What kind of setup was involved before using the product?
A: Set up for proper use here is to clean around the jack’s fill port and remove it. No “shake well” required with the HJ-12.
Q: How was its packaging?
A: The product itself is just a bottle with a stepped cap. You cut the tip off so it fits into the jack’s fill port. There is a sleeve over the neck of the bottle with useful information. I was sent a display pack that would sit on a shelf. This display container is perforated to allow easy removal of the product.
Q: Was there a manual included?
A: No manual; just usage instructions on the bottle.
Q: How does this tool compare to other tools you’ve used like it?
A: Yes, with very different results. The jack leak stop I have used in the past was thick as molasses. Using it made the jack frustrating to use, especially in cold weather. I was so disappointed I ended up flushing it all out and living with the drips. The HJ-12 has really slowed the leak and perhaps improved the overall performance of this jack.
Q: Is there any way you could think to improve or add to the tool?
A: How about an extended/flexible spout to make it easier and less messy to get into the jack’s fill port.
Q: On a scale of 1 to 10, how would you rate this tool overall? Why?
A: I give the HJ-12 a 10 for sure! Even though it didn’t completely cure our 50 ton it sure made an improvement. I would much rather spend a few bucks refilling this jack than a thousand or so replacing it.
