Defender, Discovery, Motorhome – Before n After rustproofing

Classification: c) Over 10 years old but very clean for age. Not expected to need re-treatment under the guarantee.
Has had a coating of waxoyl (not by Before 'n' After) at some stage in its life. This has preserved it well. As usual with waxoyl some dirt has been impacted into the old coating and the pressure washer does not remove these last vestiges of dirt. It just impacts them more into the coating. (Gives a somewhat dirty appearance it the photos). This is not a problem. a) the layer of dirt gives a degree of protection agains further impact and b) it will not prevent my coating from penetrating into it and forming an amalgam with any old waxoyl that has not been removed by the pressure wash.
