Defender, Discovery, Motorhome – Before n After rustproofing

Classification: b) Up to 10 year old vehicles with usual amount of rust. Not expected to need re-treatment under the guarantee.
Previously waxoyled (not by Before 'n' After). The waxoyl had worn very thin through abrasion and was still present on only about 50% of the surface. As usual dirt had impacted into it and this is alway impossible to completely remove with the pressure washer which just forces it more into the surface. So this accounts for the still slightly dirty appearance on parts of the underbody after the pressure wash. The CR coating will penetrate into the remaining old waxoyl and form a new amalgam with it. Note that dirt impacted into a coating of waxoyl will actually protect it somewhat from further abrasion.
