Fantastic results

Hello folks, just wanted to let you know how impressed I am with your “ONE SEAL Stop Leak” product. My 2010 Kubota BX25 had a leaky seal from front differential tube at the right steering knuckle. I am spot on with all fluid changes. I added one 11oz bottle of this product and ran a thirty minute job to work it through. Fantastic results. No more fluid loss and a clean shop floor to boot. Thank you!

Will be using again when needed in future

I used product #1334 One Seal on my 2003 Subaru Forester wagon. I had a leak very small leak on my radiator and I used the Bar’s Leaks One Seal. I put it in and it’s sealed it up enough where it stopped dripping and I was able to continue driving and turn the car in when I went for my new car with no leaks!!!  You guys make great products and I will definitely be using again when needed in my future.

Helped me a lot

I purchased the one-seal-stop-leak-1334. I had a valve seal leak that when I started the car would smoke and sometimes a lot for a few minutes. I put the one-seal-stop-leak-1334 and have driven it about 500 miles and it smokes a little occasionally but it’s very rare. It definitely has changed a bunch. And I know it will totally stop soon.

I got this for an oil leak, and I had my doubts because the price is so cheap. I’m impressed – works well and quickly, and it stopped my leak within 10 minutes. Was recommended to me by auto store employee. Would buy again if I had another problem. A+. I have a 2003 Ford F-150.

Affordable and effective – I tried this for an oil leak in my son’s 2005 Pontiac Grand Prix. Worked exactly as described, easy to use and install, no mess, no clean up. Worth it.
