M Seccombe July 2019 – 5 Stars

This is the best rust converter and the original. Item arrived promptly. The product does what it’s meant to do and does it better than any other product out there. 12 square metres coverage per litre. I’m using it in a maritime application.

 This product Neutrarust 661 is one of the best you can use to prevent further rust
development. I have seen this product for many years in an offshore/marine
environment and it works! Although a bit pricey its well worth it. You get what you pay
for applies here.

This works perfectly. Converting rust into an almost gloss black finish. Much more
effective than some of the more common brands stocked in local DIY / Auto Shops.
Highly recommended.
