I recently purchased some Meguairs SMR 2.0 and the orbital polisher on sale for $170 at proper auto care. The Meguiars didn't seem aggressive enough for my swirls (black car). So I've heard FI 2 is the next step. Since I'm going to apply these by machine should I use the std. white foam pad to apply and than the gray pad or terry bonnet pad to buff off? Also, how much FI 2 should I use? Finally, where can I find FI 2 online?
