Got here late to the discussion--bswombaugh summed it up perfectly and dropping to 3 drops. I clean the pad after every section. I use a Denture Brush that I picked up at the Dollar Store for (you guessed it) a dollar--holding it against the pad (with the GG on it's side across my legs) while on speed 4 then use the towel method, but find it better to twist the towel up and use the rounded ball end that forms and hold against the pad while on speed 4. Never really been able to get Mike Phillips method to work. Don't know exactly the condition of your paint, but with HD Polish on an orange B&S pad I'm able to remove wash induced marring in 4-6 passes on very hard VW clear. Also, are you cross hatching your passes--first pass left to right overlapping by 50% on each pass until you cover the entire section of paint you are polishing --the second pass top to bottom overlapping each pass 50% with the successive pass? and so on and so on---
