Hello, a rusty VW Golf (swivel and fender tip behind wheel box) makes me despair. It was tried to counteract with cleaning and wax, but did not help. The rust is there and now wanders along the threshold and also at the fender tip. The parts are screwed, therefore. My question: How do I get the wax from the parts? Warming and wiping with old rags will fold to a certain degree. After that with brake cleaner? With dilution? te? I would like to make the exposed rust safe with Owatrol and then treat it with a rust protection paint (Broxo 3in1 somehow so, forget name). Owatrol on the wax will bring nothing.
