How large of a leak does it repair?
White Shepherd will seal leaks in any fluid systems that are seeping or dripping.

How much do I use?
Use 1-8oz. bottle to treat leaks up to 8 quarts capacity.

How long does the repair take?
Start engine and drive vehicle or equipment to let White Shepherd circulate. The repair is sealed while you drive (up to 2 days drive time).

Do I have to change my oil after I apply White Shepherd?
NO. White Shepherd mixes with the oil and can stay in the system.

How long will the repair last?
White Shepherd is a permanent repair!

Can I reapply White Shepherd?
YES. White Shepherd does not contain petroleum distillates, which can destroy seals after temporarily expanding them. It is safe to repeat treatment if other seals leak in the future.

Can I use this in my brake system?
NO!
