Hello, I don't know which pads for compounding to buy. I will be using LHR 15 Mark II, will finish the paint with Rupes Yellow pad + Rupes Keramik (Yellow). Sometimes ONE STEP polishing with rupes yellow+yellow. But sometimes paint will be trashed, so I need something to cut. I would buy Rupes Blue foam, and use it with Menzerna FG400, but I heard Rupes Blue foam doesn't last too long, so it will break after a few cars? Mostly cars will be Germany, like MB BMW AUDI VW, sometimes Japan cars like TOYOTA LEXUS. Meguiar's Microfiber DA Cutting Pad with FG400? I don't know. THANK YOU!
