ATP Automotive AT-205 Re-Seal Stops Leaks, 8 Ounce Bottle

I used At205 reseal on my 91 Nissan, 300zx twin turbo. The 300 leaked oil around oil pan and probable rear main seal. This product stopped the oil leak completely and have not noticed any side affects with engine performance. Will be using again for sure! Also sprayed on all my rubber bushings leaking ttops. This stuff works!

I love at 205, this stuff works about 90 to 95% of the time. Of course it's not going to fix a big leak or big holes or cracks, but if you have a very small leak in any seals it should take care of it after one or two treatments. It fixed my power steering leak, but it took three treatments to repair my power steering leak now I have a transmission seal leak and I'm going to try it for that hopefully it will take care of it.

In my opinion, there is not another product in this utility that works better that 205. And I've tried most of them. This is, hands down, the stuff that actually works. There's not much more to say. If your vehicle is in bad need of repair, you'll know it if this doesn't work for you. That's just my opinion of course, but that's how I'd judge it. This stuff stops leaks without any noticeable effect on my engine's performance. I have an older vehicle and a wife who complains about any tiny oil drop on our otherwise pristine driveway. This stuff helps keeps the peace at our house, so it's multi-purpose in that regard. Highly recommend.

Really stopped my leaks, a little expensive but it does work.

I bought a used Tundra with 140K miles on it that I knew had a leaking rear main seal. It was a $1000 repair if you get a really great deal. I ended up getting the truck for a really good price and was prepared to get the rear main seal fixed. I ended up putting it off and it was going through a bout a quart of oil in 5000 miles. I wasn't worried. Some German cars tell you going through a quart every 800 miles is normal. WTF?My old truck had the transmission go out on the road and I had to get it rebuilt by AAmco. They convinced me to replace the rear main seal while the transmission was out even though it wasn't leaking. I continued my trip, had the transmission checked out as required. I was informed then that the new rear main seal was leaking. On my way home I stopped at the Aamco transmission shop to get it fixed under warranty. Unfortunately it was Saturday. They told me I would have to stick around for 2-3 days but they would fix it for free. They also told me that I could just get it fixed at an AAmco near home. This turned out to not be true. The Aamco near home wanted another $1200 to replace it. I wasn't going to pay another $1200 after just paying $3500 to for the trans rebuild. I ended up putting some stop leak product in the Transmission. It slowed it down but never completely stopped it.After getting a few estimates to get the rear Main seal replaced I decided to look into Transmission Stop Leak again. I found this product and it seemed better than what I had used previously and that worked OK. I put it in according to instructions and drove around with it until my next oil change was due. I took it to a local Toyota dealership which had very reasonable oil change prices, only about 5 dollars more than it would cost me to buy the oil and filter. Tundras take 8 qts of Full synthetic. They confirmed that I needed a rear main seal. I asked them what about putting Stop Leak in the Transmission. They told not to do that because there was a good chance it would ruin the transmission. Well too late I had already used it. I decided to wait and see what would happen because it had only used 1 quart between oil changes. Oil is a lot cheaper than replacing the rear main seal. I am so glad I did because as per their instructions before I went back for the next oil change I cleaned the motor off really well with degreaser and a pressure washer. This time they told me that it wasn't the rear main seal that was leaking but the Cam Towers. This was goin go be $4200 to fix. Since it was using less oil I decided to wait a little longer to see what happened. The bottom line is AT-205 RE-Seal didn't ruin my motor. It did stop the oil leaks though. Toyota told me I had very slight weepage around my valve cover gaskets but never either of the other 2 oil leaks again. I can only assume they thought I got them fixed. I cleaned up the under carriage a few more times to check on things and was amazed at how well this product worked to soften up those seals to stop the oil leaks. I now have more than 180k miles on the Tundra and the only time it uses oil is towing a trailer at 70-80 mph for long trips. This product is a bit more expensive than some of the brands but in my opinion well worth it.

I first used this on a Honda pilot that had a main seal leaking and really didn't want to mess with it. I tried this as a crazy last ditch effort, and to my total amazement, it completely stopped the leak.Then I purchased a ZTR mower and it was leaking oil like crazy. I've never seen anything leak oil this bad. It was all over around the motor and pooling up. So, I thought what the heck. I'll try some of this in there. I put about twice the recommended amount, and to my amazement, it completely dried up. I had the mower 3-4 years after that and it never leaked once. My mind was blown.So I have a complete believer in this product. It's unbelievable how well it works. It will save you tons of money and time. Give it a shot, you will be amazed as well.

I saw no improvement in performance in any area

It lessened my rear main seal oil leak by about half or sometimes very minimal overnight after I use my car. My quote to fix my issue on my 2008 Honda Fit is about $1K but this stuff is a band aid for now while I save some money. It costs that much because they have to drop my transmission to access the rear main seal. Overall im happy, inexpensive for what it does.
