Bilt Hamber Dynax UB Firm Film Anti-Corrosion Wax - 750ml aerosol

Product Information

Onto the underside, and I placed plenty of sheets of cardboard underneath to catch all the drips, as it's quite messy. I used the long wand to spray Dynax S50 into any holes and cavities I could see. I then sprayed Dynax UB over all surfaces, left it overnight, and did another coat the next day. The following day I liberally sprayed some ACF 50 over the underside to try and catch any missed areas and get into any nooks and crannies. On a really hot day when i've got nothing to do i might just shove another couple of cans of cavity wax through the chassis, just in case.

Dynax-UB is for underbody protection, forming a touch-dry, brown, wax-like film and is able to arrest existing corrosion. It provides long-term protection to pre-corroded and corrosion-free surfaces. If you don't fancy doing it yourself, I've seen a company called CSK Automotive, based in Herts, mentioned on Land Rover forums. Not cheap by the look of it and no personal experience.

I'd also suggest getting the arch covers off for a look behind. I took off my rear ones and there was a ton of caked on mud, but fortunately no rust. You can also see where the fuel filler pipe runs from there, which has also had rust issues on some cars, so you can give that a spray of rust proofing too. Dynax-S50 has been proven to substantially outperform competitors cavity waxes in salt-spray trials under conditions of ASTM B117. Here are the results: The product is made without any water displacing solvent, this is intentional so that early water resistance is made on exterior surfaces. However if there is any moisture left - (this time of year with atmospheric water and colder panels water can remain on surfaces for hours) the product cannot adhere properly and will form a wax skin effectively floating over the moisture. Any traces of surfactant left from Surfex would've allowed the water to become very lubricious too so the film would sort of move. 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%. We run older cars, we buy as well looked after as possible when the right car comes along, then because of the UK's salt fetish some serious rustproofing gets done then we run them as long as possible.

It is recommended to place the container in a room at around 15 degrees C for 24 hours prior to use, particularly when using low pressure equipment for spray application. There's a round cross member linking both sides of the chassis thats hollow just in front of and above the rear wheels, so it was interesting to watch the spray silhouetted aginst the light from the other end. Follow that up by treating everywhere with Electrox. It's a fantastic Zinc Treatment. They sell it either in an aerosol or in a tin, which can be brushed on or thinned down and sprayed on. If you're spraying it on then thin it down with pure Xylene, not regular thinners. Again, give 2 coats.

Dynax-S50 is an anti-corrosive wax product for rust proofing. It provides exceptionally long lasting protection to steel surfaces. https://cdn.opieoils.co.uk/images/variants/icon/bilthamber/bilt-hamber-dynax-ub-non-aerosol-5-litres-7.jpg https://cdn.opieoils.co.uk/images/variants/large/bilthamber/bilt-hamber-dynax-ub-non-aerosol-5-litres-4.jpg I popped the treadplates off the front to see if there was any way to spray Dynax S50 into the sills, but no joy. Under the rear plates there was a hole that the S50 long wand would fit in, and so I sprayed some in there as best as I could.

I'm using the Dynax UB myself for the underbody and arches but unfortunately don't have any test on the road as car it's off the road at the moment,however I'm prepering some mild steel plates to test impact resistance,scratch etc. https://cdn.opieoils.co.uk/images/variants/large/bilthamber/bilt-hamber-dynax-ub-non-aerosol-5-litres-1.jpg Unlike traditional bitumen underseals dynax-UB will not peel. Peeling underbody coatings trap water against the steel surface accelerating corrosion. Dynax-S50 is tolerant of a broad range of application pressures and will form a coherent film upon application. Dynax-S50 will increase in viscosity at low storage temperatures. Dynax UB is not a hard or brittle film it's a firm waxy calcium soap and very flexible. You can pull your finger nail through it but would never normally be able to lift the film in the way we see here - we've never seen it before!The advanced metal seeking anti-corrosion molecules which form Dynax-S50 are able to displace water, so even damp surfaces can be protected, these same molecules arrest and prevent corrosion even on already rusty surfaces and provide remarkable self-healing abilities if the film is damaged. Whilst Dynax-S50 is primarily a cavity rustproofing compound it’s also able to prevent corrosion in a multitude of mud traps and water collecting voids. Dynax-S50 has been used with superb results to protect voids and cavities in steel boats, vessels, offshore installations and other steel structures subject to severely corrosive atmospheres.
