Underbody Protection. (Waxing)

Please read this as it is important! Armson A.E is not a endorsed treatment center or any other form of underbody treatment!  Our unique treatment process and stages of application have been developed by us to allow us to treat your vehicle and because of this we are confident in the process to offer a 5 year warranty but… see warranty at bottom of page.

We have for the last few years been a very big advocates of the Dinitrol products but as with everything, changes happen with the quality of the product and we felt it was time to change!  FOR ALL OUR CUSTOMERS WHO HAVE PREVIOUSLY BEEN TREATED WITH DINITROL, THE WARRANTY AND RE-TREATMENTS WILL BE DONE WITH DINITROL AND DOES NOT EFFECT YOUR WARRANTY WITH ARMSON A.E.

We have tested a new rust converter which we are very happy with.   We have also changed to the NOXUDOL  system and this allows us to up our game yet again and offer a 4 layer system!


the pictures and stages below are of the old system and will be updates of the new system in action over the next few months.

What do we offer that is different?

On receipt of the vehicle to be treated we strip & remove bumpers, exhaust, wheel arch liners, door cards, tailgate trims, sill trims/protectors if required, headlamps and rear lamps, grills and any other trim that we think will prevent us from obtaining access to the numerous cavities and crevices located around your car, 4×4 or commercial vehicle.

Stage 1.

We steam clean and degrease the whole car top to bottom.

Stage 2.

With a wire brush we remove badly corroded areas or simply clean where the steam cleaner could not reach then leave the vehicle to completely dry. Once dry we protect the out side of the car with protective dust sheets and inside the car as well.

Stage 3.

Our treatment application technicians apply a rust converter and allow 24 to 36 hours for the product to cure.

stage 4.

For the next stage we apply a cavity wax with super penetrating corrosion prevention coating and allow 24 hours to cure.

Stage 5.

We then apply top coat,  with corrosion prevention wax to form a second coat and allow 24 hours for the product to cure.

At this point it is worth pointing out that we can spray the wax coatings back to back but this does not allow time for the solvent to disperse and can lead to poor adhesion between the two layers so allowing 24 hours between coats give the maximum chance to adhere to the sub-straight(chassis) and each layer.

Stage 6.

In the final stage we refit all the removed trims and parts and then wash the car thoroughly to ensure its completely clean before returning the vehicle to the customer.
