If applied with RO/DA, will Klasse AIO be enough to clean up some light spider webs and swirls? Or should I just bite the bullet and go straight to Sonus SFX2 first?
Also - this will be my first machine effort - how do you know when the polish etc you are working has broken down sufficiently to do the final buff by hand. I've seen a few vids but can't really tell at what point to stop...
