Finally got round to cleaning my poptop roof. Being black it was looking very sad. Flat and dull with years of grime. Had tried everything under the sun previously to no avail. Spotted Meguiar's Marine RV 49 Boat Oxidation Remover over winter which I have used today for the first time. Certainly cuts through the layer of dirt built up over years and brings finish back nice and shiny. Finished off with a polish coating and a layer of wax. See how long it lasts now. If not successful will be vinyl wrap next time.
