Casechemicals Reviews 2

1. On 2005 sprinter, renowned for rust I annually keep it to a minimum.
2. Corraseal recommended by car body sprayer as it is also a primer (his understanding)
3. I am no expert, do not know what advice given to previous teview but I have seen special paints for chassis.
4. Also good to sand/grind back to bare metal, removing all bubbled paint and rust.
5. Shall continue with Corraseal as it suits my needs and I have tested no others.
6. Would appreciate recommendations of other products.

Bought this product to deal with rust on a car chassis in late 2021/early 2022. It seemed to be the best product out there for stopping rusting of mild steel and preventing further rusting - given that it's recommended for protecting ship hulls in corrosive salt water you'd think it would work - right! Wrong!

It wasn't cheap but I didn't want cheap; I wanted a product that would work so I paid the £41+ for the 1 litre bottle which duly arrived.

I waited for the middle of Summer 2022 to use the product during a dry warm spell then went to work removing as much of the rust from my Mondeo's rear subframe as I could and then making sure it was free of contamination before applying the product as suggested using two coats. It looks spectacular - product painted rusty metal goes black so it appears to do it's work. I gave it 24 hours to thoroughly dry before applying several top coats of oil based (as recommended by Corroseal) black chassis paint. I thought that would be the end of the rusting of my subframe - wrong!

And so followed, the usual winter, where as soon as there's a hint of the temperature dropping towards freezing, the local council liberally slather the roads in salt. At the end of the winter, I had a look underneath the rear of the car and was extremely disappointed to find that it was corroding again in all of the treated areas.

So, Case Chemicals, whilst I'm aware you are only the importers for this product you need to be aware of this experience. I did the work as directed and it has failed to do the job. I certainly won't be buying Corroseal again.
