Everyone here says use Dinitrol (at least no one suggested Waxoyl), but I assume none of them have read the July 2013 report by Dr Phil Green from the University of Hertfordshire School of Engineering and Technology called "Assessment of Wax Coatings Using a Salt Spray Cyclic Corrosion Test".

In this, six well known corrosion protection products were each put, at the same film thickness, onto three identical bare steel plates, along with one steel plate left bare, and subjected to wet salt spray testing in a controlled environment. After the time was up, the products were cleaned off and the amount of corrosion assessed.

The results, after 2084 hours of testing in a ridiculously harsh environment, put Dinitrol 3125HS in 4th place, with Bilt Hamber's Dynax S50 a comprehensive 1st. There was the barest trace of rust on the very edges of the plates coated with it, whereas the Dinitrol had around 75-80% corrosion under it. Waxoyl was 98-100% rust incidentally.

The test was done at the request of Bilt Hamber, but I can find no hint of any bias towards them in the report. It's all backed up with multiple photographs of the results.

It's your vehicle, and your money, but if you want the best corrosion protection you can get for it, Bilt Hamber is the firm to use, and they're British too:

If you contact them, they will probably let you have a copy of the report. It's a real eye opener.

It's easy to do it yourself with their big high pressure aerosol cans as they come with 2' tubes with diffusers on the ends to get into all the awkward areas. Peter Hamber suggested to me to use Dynax S50 inside the 110's box sections, and Dynax UB on the exposed surfaces. I'm going to use the UC to protect the less exposed mechanical assemblies too.

Having previously tried various alternatives, I've used BH stuff on my vehicles for eight years now, and wouldn't entertain anything else. And no, I'm just a customer, not an employee (although I ought to be on commission!)

I hope this is of interest.

Joe, surely of interest. Surprised this was never brought up before. But if there is such a comparative test done, with Bilthamber coming out tops, why don't Bilthamer put an easy link to this report on their website? Cannot imagine any better advertising than that, no?

Does anyone do a clear/transparent rust proofing product?
