Well I tried Zaino 2 months ago, did exactly what their directions said.I washed it with Dawn, clay bared the whole surface. I had some minor swirls in the paint which the Z5 did hide after 2 applications. Then over the course of 2 days I had 3 applications of Z2PRO. The finish was exactly what I was looking for. Now after 1 month the paint still beads water high and still has depth but I can see all the swirls again. Are the swirls from washing/drying. I use a waffle weeve to dry and a very plush wash mit (both from MOTHERS booth at a car show).
