I'm preparing to invest in a DA polisher set-up to take care of the family cars once winter passes. I'm wondering if my Festool Rotex RO90 would be a good option as the small throw, small pad (4") DA polisher to compliment a long throw machine like a Rupes Bigfoot or GG Boss DA? Anyone have any experience or knowledge of using this particular Festool Rotex machine for car detailing? Thanks much.
