Months ago, the last product that went on my car was 3M Imperial Hand Glaze. After much DC reading, I've decided to go over the car again this spring as follows: wash, clay, SSR1, AIO and UPP. My question: Since I'm not going with much of an abrasive, do I need any special steps to get rid of the fillers left from 3M IHG? does washing with Dawn do anything? should I wipe off with alcohol/water mix? or will the clay and SSR1 remove any remaining fillers? Thanks in advance!
