Roger,
Not knocking you for going by hand. I've enjoyed it thus far, but HAD to try it given the results I've seen.

White does seem to get dirtier. I've detailed white and for some reason I seem to "pick up" more dirt than other colors.

PC does not change the order you do things. It merely replaces your hand applications for a more efficient and faster application.
I think my plan of attack for the 95 will be:
1. wash
2. clay
3. Menzerna Final Polish II by PC
4. AIO by PC
5. Four Star Ultimate Paint Protection by PC
6. Natty's Blue by PC
I'll be sure to post the results.
