I have a Parkside (Lidl) polishing set which I bought some years ago for a job for which I couldn't find a round tuit.
It has a felt? polishing wheel, a buffing wheel and two bars of polishing paste - brown pre-polishing and light blue post-polishing. They're like thin bars of soap, feels like a hard wax, presumably the brown one contains iron oxide.
How do you use these? Do you apply them to the wheel, do they need heating up to soften? There are no instructions.
