We've returned to Japanese cars, after many years running mainly Merc W124's only one of which we still have, it's been a pleasure to work on cars designed to last and be worked on and fixed in the field again quite apart from the engineering of the marques involved. Well I'm not really any clearer to be honest. Some saying to avoid Epoxy Mastic like the plague and others (including Mr. Hamber himself) saying use it...I noticed dynax s50 mentioned in a few places and started looking into it a little more and the review on here by Neil_S and a few other posters (Petrol on sxoc) have me convinced this is the product to use over a waxy type cavity wax. The final picture in the series below shows Dynax-S50 protected metal is still in exceptional condition. https://cdn.opieoils.co.uk/images/variants/large/bilthamber/bilt-hamber-dynax-ub-non-aerosol-5-litres-2.jpg

After solvent washing the panel fronts any remaining waxy film is removed, allowing inspection of the underlying surface. Assessment of the product performance is then easy.As you can see from the salt-spray test demonstration, Dynax-S50 clearly outperforms other highly rated cavity waxes. Infact, after much testing Dynax-S50 was presented with the best cavity wax accolade from University of Hertfordshire – School of Engineering and Technology.The graphic below shows Dynax-S500 treated on half a metal panel after 2084 hours in the salt spray chamber. We competed with six other rated cavity waxes in this extensive test, including brands such as Robuster, Hammerite and Mike Sanders.

Bilt HAmber Dynax-UB forms a touch-dry, brown, wax-like film. dynax-UB is able to arrest existing corrosion and to provide long-term protection to pre-corroded and corrosion-free surfaces. https://cdn.opieoils.co.uk/images/variants/icon/bilthamber/bilt-hamber-dynax-ub-non-aerosol-5-litres-5.jpg https://cdn.opieoils.co.uk/images/variants/medium/bilthamber/bilt-hamber-dynax-ub-non-aerosol-5-litres-3.jpg It creeps into welded seams and seals surface defects. It forms a soft, brown, wax-like film that self-heals in the event of disruption. https://cdn.opieoils.co.uk/images/variants/medium/bilthamber/bilt-hamber-dynax-ub-non-aerosol-5-litres-6.jpg

How To Use

I think that Dinitrol is superior to Waxoyl - it's lasted a lot longer on the bits I've done with it, and the can I have is years old. I will have to give Bilt Hamber a try next time I get underneath. By sound basically, yes testing the spray from the probe proves a good spray pattern, you can hear where the spray is inside the chassis and sills, and see the mist and sometimes a squirt appear out of any holes as it passes by, i gave a couple of passes each time with the probe at a different angle to be sure...obviously warmer weather helps. Short of using an endoscope, how do you know that the wax has got to where it needs to go in the chassis cavities? I suppose that you must test the nozzle first to see how well it sprays. Bilt Hamber Dynax-UB is a high-performance anti-corrosion wax that provides exceptionally long-lasting protection to car underbodies & steel surfaces.

Next day, was the turn of the silicone spray, obviously taking care to avoid discs or places that could contaminate discs from run off etc. I also sprayed the insides of the alloys, the plastic liners, and various underbody bits including bolt heads etc. ( but NOT wheel bolts). Also plastic front grillwork and engine compartment plastic bits. Wiping to polish and remove excess, you soon feel how slippy the surfaces becomes When I bought the fabia estate to add to our fleet, it was still summer. I decided to strip off the alloy wheels to paint the rear drums, and then in a fit of OCD decided to go a lot further. As the suspension was still factory fresh, I could see the welds were poorly painted and generally everything very thinly coated. The exhaust rear box was already rust stained. As I know from experience, all vag cars rapidly end up with shabby rusty suspension and brake work, not covered under warranty. Unlike traditional bitumen underseals Dynax-UB will not peel. Peeling underbody coatings trap water against the steel surface, accelerating corrosion.
