Mike:
Glad to see you posting after your back issues.
Some questions:
1) I assume the "6" you refer to is Griot`s 6" Random Orbital. Are you using 6" backing plate and pad, or something smaller and in what polishing senarios are you using this in?
2) What specific manufacturer`s (s`) microfiber pad(s) are you using?
3) Is this black Porsche paint/clear coat of the ceramic type and very hard (Mohs scale)and hence, difficult to correct OR
were the swirls and (I assume) random-isolated deep scratches too sever to correct completely, or a combination of both??
With your back issues, have you changed any of your polishing ergonomics and techniques to make it easier on yourself OR are you just not polishing for a great length of time as before? IE, when it hurts, you stop and rest.
Many novice detailers or those who do detailing occasionally do not realize the physical demands on the body, especially the hands, back, and legs. My legs cramp up after a full day`s worth of detailing and it is a very painful experience. Part of that is age, part being out-of-shape and moving around like I am not used to (stooping and kneeling), and part not drinking enough water to stay (properly) hydrated.
By the way, EXTREMELY nice work on my personal dream sports car, the 911. I`ve always said that the best cars get detailed by the best detailers. This thread and your pictures are a verification of that statement.
EDIT: Please do not tell me this was a Boxer and I cannot tell the difference between a 911 and a Boxer. Some Porschephile morphodite I am.
