Newbie needs support from you!

Hello, I need your help. I want my car soon when the weather gets better Outside times thoroughly clean, polish seal etc. So my car (Passat 3BG, black) one looks at its 230 TKM, especially at the hood! Was constantly cleaned in the washing system with the lance (many bars or as one calls it). Has suffered some scratches by the children and it has become slightly matte too. My question about this what else do I need now. You will now get me mmt refer to the SuFu or the FAQ and I have read that only now I am even more confused than before with all the products and understood. Which PADs I should take now and for which cause the pad should be. Everything has just confused me more honestly said. What I already own: Vossner 6800 Eccentric Polishing Machine (through a friend) No pads, no polishing agents I hope you can help a newcomer
