I recently purchased a bottle of your Seallube for a leaking floor jack. I added 1/2 ounce of Seallube to the jack and topped it off with hydraulic oil and pumped the jack up and down several times to circulate the oil through the system. The next day I checked to see if it was still leaking and it was no longer leaking! I just wanted to say I really like your product and will spread the word about how well it works!!! I just ordered a second bottle for my neighbor who has a small oil leak on their car. I believe the leak is coming from an o-ring. Just wanted to tell you I really like your product!!! Thanks
