Our 1968 Roadhaven caravan is in exceptional condition for its age as it has been under cover all of its life except when it was used for holidays. The exterior however did show it age with 52 years of oxidation build up on the aluminium cladding and the stainless steel roof so I decided it needed to be brightened up. With 2 buff/sanders, an electric drill, various types of polishing mops, microfibre clothes/rags, a couple of 1 kg tins of Autosol and a couple of bottles Purple Polish I was ready to start. On Good Friday I started the job thinking about 3 weeks should be enough time. How wrong could I be as of today I am about 2/3rds finished, but it is looking good. The amount of black residue that is created from the oxidation and polish is unbelievable.
A couple of photos with before and after you see the difference the polishing makes.
