Meguiar's ScratchX 原廠說明就有提到 http://meguiarsdirect.com/detail/MEG+G10307 remove fine scratches and swirls from automotive paint by hand and now also by DA polisher 可以用手,或是用 Dual Action 型的機器(G110,PC7424,UDM之類的)
另外 Autogeek 有提到 http://www.autogeek.net/megscratxfin.html If applying SCRATCHX to your entire car, remember to work one section at a time. 如果你要整理整台車,建議一次做一小塊區域,然後分次處理。
