So I have the PC swirlbuster kit. It has the SFX1 and the Swirlbuster polish.



The Swirlbuster is equal to SFX2 but has acrylic fillers, from what I`m told.



So, I do the SXF1, then SFX2(Swirlbuster) but, do I really need to follow it with SFX3?



Can the SFX2 if worked in enough, give me a perfect mirror finish on lets say black paint, or does the perfect finish come into play only after the SFX3?



Also I have Klasse AIO. Can using the AIO be substituted in place of SFX3?



Do they have equal `grit` power? Thanks detailing gurus :buffing:
