This article compares the three types of RUPES BigFoot polishers sold by DetailDawg in Portugal and Spain, directly answering the questions most buyers have before choosing a machine. It explains why the orbital polisher, also called dual action or random orbital, is safer than the rotary: the pad can stop spinning when it encounters resistance, which drastically reduces the risk of burning the paint, making it the recommended choice for beginners and for most maintenance work. It also explains why the gear-driven polisher exists: a gear system forces the pad to always rotate, even on curved panels where a free orbital tends to bog down, offering more correction capability than the orbital with more control than the rotary. The article clarifies the difference between 15mm and 21mm orbit pads, explaining that 15mm favors precision and detailed work while 21mm favors coverage on large panels. Finally, it describes when a rotary polisher makes sense, despite the greater risk, due to its superior correction speed on deep defects. Each section links to the RUPES models available in the store: the LHR15 Mark V and the LHR21 Mark V as orbital options, the LK900E Mille as a gear-driven option, and the LH19E as a rotary option. The article concludes by always recommending decontamination before polishing and paint protection immediately after, with links to the corresponding DetailDawg guides.
