Please don't apologize for any question but do let me know if I didn't help out.
Polishing the paint (ie removing swirl marks) requires a different technique then applying a wax (or sealant) with the machine.
When polishing out swirl marks, the technique tends to be more aggressive. Move slowly (about 1-3 inches per second) with medium pressure (about 10-15 lbs) and work in repeating overlapping passes over a small area, until the polish begins to look clear. You will want to use speeds 4 to 6.
When you are polishing like this to remove damage you want to use the machine as much as possible to take advantage of the increased power. Use painters tape to mask off the trim and the edges so you can work the machine into the tightest area possible. Some areas may require hand polishing. I personally like to do these area's last, because I like to see what I can get done with the machine first.
When applying a wax or sealant the goal is lay a very thin, very uniform film of product on the surface of the paint. Use a very soft pad (Lake Country Red or Gold) on speed 2 or 3. Overlap each pass as much as necessary to ensure even coverage. Instead of working a small area at a time, you will work until there is no longer product on the pad to spread around, usually about a 1/5 or 1/4 of the car.
When applying a wax or sealant with a machine I will use a hand applicator to get to the spots that a machine cannot reach. In this case I will usually do this part, going around vents, girls, jambs, etc, then using a machine to cover the rest of the area. This is simply a matter of preference, what is more important that all areas of the car are protected.
Best of luck and see what works for you!!!
