One-step polishes

Hello together, can you reveal with good one stop polishes (polished + finish in one) that also eliminate scratches on hard varnishes well? I am therefore on one stop polishes, because I would be extra polish (with my own polish) and extra finishen (with another polish) would be far too time-consuming. One has to drive several cross strokes per polishing process and that on an area of only 40×40 cm. I polish with an eccentric polishing machine and yellow pad (i.e. the hardest powder another question: When polishing with an eccentric polishing machine you should apply a pressure of approx. 5kg. on the polishing machine. That’s not a little. After half the bonnet already rip my hands off. 😉 Do you have a trick in stock to polish the car as forceless as possible? Thank you in advance for your tips. LG Didi
