Metallic Seal Up
In just a few simple steps, our product will seal up radiator, freeze plug and heater core leaks in 10 minutes (head gasket, engine block and cylinder head leaks are sealed in 10 driving miles). Not only does it do the job, but it can also remain safely in the cooling system for future protection.
Leaks within your vehicle’s head gaskets, engine blocks or cylinder head can cause trouble. That’s why we developed our Motor Purr Metallic Seal Up. Not only is our special formula guaranteed to stop all leaks permanently, but it is also the only metallic sealer in the world that mixes with all types of anti-freeze.*
*Other seal up products containing sodium silicate, or “liquid glass,” are NOT compatible with ethylene glycol (the main ingredient in anti-freeze); mixing these two chemicals can plug up your cooling system.

Reviews
Many years ago I used purr sealer for a huge freeze plug leak on a 350 Chevy truck stopped the leak and lasted for many years including lots of boat towing. Many years later used it for a significant radiator leak on a V8 ford and has lasted for years and still to this day. Sadly I got the two bottles recommended for a head gasket leak on a V6 Toyota followed instructions to the letter and was unsuccessful at stopping the leak. Don’t know if it was a gasket or a warped head.
Got a bottle of this as well as a bottle of tune up. The seal up works great. Both my head gaskets were leaking and after putting this product in, I see a big difference. I will be a customer for life
Seems to have worked for my head gasket issue. So far so good
