i own a festool ets150/3 fiotted with 6" backing plate and a white "honeycomb" waffle sponge. Applying Zaino -PC by hand to my 2010 Mercedes E350 cdi estate has had little effect on paintwork. I am thinking about using my ets 150 instead of my hand to improve the paint finish. You do not state that an ETS150 is ok for car body. Can I use the ets 150 on car paint?
