Dynax S-50 Anti-Corrosion Wax (750ml)

Does exactly what it is intended to do , a modern day product that improves on the old methods of protection - applied easily with the flexible wand and gets into small and tight spaces .

Sprayed inside door sills easily with tube attachment. Arrived well packaged.

Probably the best cavity corrosion inhibitor on the market. Easy to apply, expels moisture effectively and long lasting (as long as its not exposed to sunlight but then again, it's for cavities, so that's ok). Used on a 25 year old Ducato and it stopped existing corrosion in its tracks. I use it on all my vehicles now.

A little thin but very easy to apply and the cavity tube is great

Used inside the sills and cross members of our transit camper. Covers well seems good quality

Looking up the best products for preventing rust, these Dynax products seemed to have done about the best in some forum tests. I bought the S50 and UB sprays for my car.. I can't remember which is which, so here's a bit about both. They're messy to apply (like all other sprayable rust stoppers), but they do seem to spray well, unlike the waxoil spray cans which come out like a bobby horribleness. The Dynax cavity wax has a long hose with a small brass nozzle for reaching through sill drains and trim fastening holes (I bought 2 and used one nozzle to spray epoxy primer in the repaired sill a couple of days before the dynax). The normal Dynax spray protector comes with a normal spray top which was fine in use too.

Easy to use and clean to use. The supplied application lance works well and is long enough to get well into box sections etc. Seems to be a quality product and hopefully will help protect the steel.

Used it for years. Treat my pick up & classic every year. Easier than others to apply, looks great & really does seem to work given the condition of the undersides. Pick a warm, dry , windless day, dress in old clothes , hat , goggles & mask. Almost a pleasant job over just a couple of hours. Then shower!
