I usaully use
UDM & IP with 6.5' CCS orange pad to cut the swirl mark and then follow by FP with 6.5' CCS white pad then i clean the paint with 6.5' CCS gray to remove the dust & oil before i seal or wax the paint.
Then i apply the wax by hand with applicator. For perfect finish, I like to buff of with UDM on speed 4-5 with 6.5' CCS red pad.
I just had a
Sonus SFX1 & 2. I did tested on just a half of panel to see how it work. I did it with CCS 5.5 orange pad. I found the SFX cutting very well and the cutting time is short and dry very fast if compared to IP or SIP. But overall is very good polish good quality product to me.
