You want a mitt that doesnt hold onto grit and dirt, one that easily releases it in your rinse bucket....i use and love sheepskins, search Schmitt..or the grout sponge at HD or w/e is big and porous. wash media is personal preference you just want something that releases the dirt and grit from itself so youre not rubbing crap into your paint as you wash. Claybar again is perference, 3m makes decent clay, Mothers clay kit avail OTC is pretty gentle and has everything you need with a QD and clay in the kit. I use Sonus green myself. Drying towel again is personal preference but again you want something that isnt going to marr your paint as you dry. Kmart and Sears have a kit for 9.99 from Viking brand that has a huge drying towel some MF apps and a mitt and 3 towels or so.. But read up use the search function but we are here to help regardless. Excel is a great place to get stuff cheap.
