Key Advantages


Proven for over 35 years – requires minimum preparation so reduces prep time

There is no other primer coating like it

Try our challenge:

1    Take some rusted steel and remove loose or flaking rust with a wire brush.

2    Paint on a thin coat of Neutrarust 661 and leave to dry for an hour.

3    Now take the wire brush and try to remove the coating. (It won’t come off!)

It is quite simply amazing that Neutrarust has such strength and adhesion after such a short time.

This simple test proves how good Neutrarust 661 is as a primer – even directly onto rust!
