as title had a bad rear ace leak and small front one coming from ace cylinder put this stuff in pretty expensive but peanuts compared to new ace bars and fitting been nearly a year now and 12000 miles later and is "dusty" dry not a drip and car is used off road most days, def worth a try may take up to 2 weeks to seal so stick with it

Hi, thanks for the information.

I'm glad this has resolved the issue in the short term for you

The key thing to consider here is that these fluids should be considered a short term workaround and not a fix to the root cause of the problem. Putting these magic fluids into the system causes the seals to swell which may stop the leak, just like in power steering systems. However, it would always be recommended to replace the faulty part as soon as is practicably possible. Kev
