With the arches looking alot cleaner, I then removed the wheel arch liner so I could clean and get the Dynax S50 in those hidden places.

It is also able to arrest existing corrosion and to provide long-term protection to pre-corroded and corrosion-free surfaces. is a high-performance anti-corrosion wax that provides exceptionally long-lasting protection to steel surfaces. I literally filled the heater channels on my beetle with Waxoyl when I finished it in 1994 and they are still good 20 years on, despite being repro panels.

Wirebrush the rust off, treat it with a converter like Hydrate 80, then a decent paint, then the Dynax.If you decide to treat your car or vehicle to additional corrosion treatment its important to select a cavity wax that can penetrate into welded flange seams these are the areas proven to be the first to corrode in fact the Swedish Corrosion Institute conducted a thorough investigation into vehicle corrosion by sawing open the bodies of 845 collision-damaged cars manufactured between 1994 and 1997, the corrosion observed in the flanges and seams resulted in the recommendation that even on cars with reasonably good cavity fluid treatment applied at the factory a complementary treatment be used within 3-4 years of manufacture. Dynax-S50's soft-film is optimised for enclosed cavities where extremely corrosive conditions develop. Dynax-S50 has a high solids content – over 50%, it’s this content that forms the anti-corrosion coating, and whilst other high solids materials don’t penetrate sufficiently Dynax-S50 creeps by capillary action deeply into seams, flanges and folded edges, in side-by-side trials Dynax-S50 has been proven to creep significantly further than other cavity waxes, some with solids contents as low as 25%.

Dynax-S50 is a high-performance anti-corrosion wax that provides exceptionally long-lasting protection to steel surfaces. Whilst dynax S-50 is primarily a cavity rustproofing compound it’s also able to prevent corrosion in a multitude of mud traps and water collecting voids. Way over the top I know, but as far as I can tell no rust has developed since, which isn't bad on a 1970s british car! The capillary nature of Dynax though, means that it does heal itself and even if unnoticed, the breached area will reseal.

As paradox says, I reckon how you do it matters more than the product - getting into all the box sections and covering them inside. Whilst Dynax-S50 is primarily a cavity rustproofing compound its also able to prevent corrosion in a multitude of mud traps and water collecting voids.
