About Us


I am Matt Ferris, owner of Aussie Stop Leak. I am a fully qualified Automotive 

Engineer/Motor Mechanic and have worked in the Industry for over 30 years. I owned and operated Riverstone Radiators, a fully licenced auto repair shop in the North Western region of Sydney.

During my time in the workshop and the radiator shop I quickly discovered that an affordable, easy to use and effective stop leak was desperately needed, but most importantly a stop leak that would not block or harm your radiator or engine in any way, as this is the case with many of the other stop leaks on the market today and that had been used by so many of my customers.

I then set out to develope my own, new and improved product and now after four years of development, extensive tests and trials, it is to be marketed by me and my family as Aussie Stop Leak. My product is one of the easiest to use on the market, it is the most widely effective, and also is very competitively priced with all other cooling system stop leaks available.

Because Aussie Stop Leak is a dry product in a plastic sachet it is ideal for keeping in storage for example, a glove box, a compartment in earthmoving equipment or even a backpack on a motorcycle.

This product is of course 100% Australian. It has been developed from a genuine need, not as a gimmick or a quick money making venture. We have many happy customers already throughout our trial period and feel that we will have many more as the word spreads.
