Product Description

Re-Seal is a special plasticizer which softens and expands hydraulic seals to stop leaks. It will work on any hydraulic system (except brake) including jacks, lifts, plows, and industrial equipment. It works quickly (engine main seals will require 5 hours of running time) and will not cause the seal to become gummy or break down like other products.

Had oil leaking from rear main seal in '03 Maxima and got 5 estimates to replace in the $700 to $950 price range. $42 part and the rest was labor. One mechanic suggested I try AT 205 first so I stopped by his shop and bought a bottle. I don't like using any engine additives but he said he used it in one of his high mileage personal cars with good results. Poured it in and over night the leak was gone. That was 3 weeks ago and no more oil spot in the driveway...

I put the 8 ounces bottle into car engine and it helps. There is an acceptable itsy bitsy leak left. You can watch "Fixing Oil Seal Leaks Fast" video on YouTube by scottykilmer. You need 8 ounces for car engine or transmission usage, and 3 ounces for power steering. I am going to order more for power steering and transmission usage.

Petroleum distillate rubber conditioners will temporarily soften rubber seals, then turn them to mush over time. Not AT-205 Re-Seal! I've used this in two motorcycles (31 and 27 years old), as well as two cars (a 1996, and a 2003), over two years ago, as a preventative measure. No problems, no issues, other than it helped eliminate one oil leak. I originally found this product in an auto-parts store, for around $7 more than I paid here (minus S/H). Even with the postage fees, this came out to be $6 less, per bottle, ordering three at a time, than I would have paid buying it semi-locally (had to drive to a neighboring town, 40 miles away -- no one locally carries it).

This stuff is non-toxic, and it is NOT made from petroleum. I don't know what is made from, but I know it works, as described. I recently had an O-ring that was shrunken, and leaking oil, on one of my motorcycles (previous treatments didn't reach this part which is more external). I traced the leak to the proper O-ring, cleaned off the oil from it, and then I wetted it with AT-205, using a paper towel soaked with it. I waited 20 minutes, then I put the O-ring back in place, and secured the part into place. I ran the engine for 10 minutes, without any signs of a leak. I then let the motorcycle sit overnight, and 5+ days later: no leaks, it is completely dry, where before, I would find oil pooled beneath the side-stand, in my garage.

I am now using it in both motorcycles' crankcases, as well as both cars' crankcases, and both automatic transmissions. I don't have any leaks, but I want to keep it that way! I would recommend this product to anyone. It is safe, and it is effective. Cheers!

I have a 1994 Hyundai Scoupe that I use for short trips around town and back and forth to work. My old friend sprung a leak from the rear main seal that was DRAINING oil at approximately a quart in 15-20 minutes with the car running. I took it to a garage and they wanted more money to fix it than the car is worth. The first day I used AT-205 and ran the car for an hour and a half the leak stopped. However, the next time I started the car to run it for a another hour or so the leaked returned so it appears that AT-205 was only a short term fix. The bottle says it takes 5 hours to seal a rear main leak so I may run it for another hour or two and see what happens. All in all, it's still worth $10 to try as long as you buy it with the understanding that it is not going to fix a completely damaged or crumbled seal. I may take another reviewers advice and try a second bottle since the leak did stop after the first bottle but later returned.

Update (12/31): I was on my way to bring my car to a garage for repairs. Before going I refilled my oil with the oil / AT-205 that leaked out the second time I started the car after adding AT-205. On my way there I decided to pull over and look for a leak. To my amazement, the once gushing leak from the rear main seal was reduced to a mere drop at a very, very slow rate. I noted one review said it took almost three weeks for their leak to completely stop so I'll continue to drive the car and update accordingly. At this point I would have to say the AT-205 actually works. My car's oil leak was about a quart every 15 minutes and as of today has been reduced to a mere drop every 10-15 minutes.

Update (1/1): The leak returned. The car is in the garage for a rear main seal replacement costing $400. Do I regret buying AT-205? No.

My car has a lot of squeeking noise that irritates me and i don't want to bring it to the dealer or repair shop coz i can't afford their price. I google it and found it in youtube, [...], Scotty Kilmer said to spray ATP AT-205 Re-Seal on all rubber bushing, it rejuvenates the rubber...no more squeek....It works!!!

My son, who is a mechanic, recommended this product to stop my leaking transmission. I would have paid over $100 to have the seal replaced but instead I paid about $10 for a can of AT 205 Reseal. This stuff is not easy to find in stores; I tried a few different auto parts stores and they never even heard of it. I highly recommend it to anyone who has a leaking seal on an engine or transmission. My son said he has used it to repair all types of seal leaks and it works every time. Now I just need to find a cleaning product that works just as well at removing oil stains from my driveway!
