I wonder how many snakes are needed to fill a 950ml bottle?
It's definitely good stuff but I'm not sure it ought to be compared to WD40, they are really designed for different purposes.
Absolutely right, Steve. WD40 is great stuff, but it was never designed as a long-term corrosion protection agent.
A good few years ago I did a test with a sheet of 20 gauge steel. I covered a quarter of it with WD40, a quarter with Waxoyl, a quarter with Dynax S50, and left a quarter bare. I then left it out in my yard for a few months.
The results were pretty much as you expect, the WD40 quickly washed away in the rain and that area rusted as badly as the bare metal. The Waxoyl lasted longer, but still not great, and the Dynax was still doing a great job of protecting the metal a year later. I've got some pictures somewhere, I'll dig them out.
