I called Ron at Nuvite and Bill Clapp to get more tips after my experience of two days ago. As everyone says, the most common mistake is too much polishing compound. Also, it is important to pat our all the spots of compound with the twilled cottom buffer head before turning it on, to avoid throwing compound everywhere. My results were much better (and cleaner) tonight. Once I undo my mistake of swirl sanding everything on the left flap topside, it should go a lot more quickly. I'm taking more than one hour per small section to sand out the swirls with grits that start as course as 600 and go to 4000. I won't make that mistake again. I'll find new ones to make!
