It's my understanding that the average/medium clay bar will strip wax/sealant during the claying process - please correct me if I'm wrong on this. My question is will a finer clay like the Pinnacle Ultra Poly variety leave waxes/sealants in place? I'd like to use the Ultra Poly every month or two in addition to a medium grade clay twice a year but not if I have to reapply sealant that frequently. Much obliged for your input!
