1997 BMW 528i. I see this one once a year in the summer at his Dad's law office...along with up to as many as 19 others! Since they have so many cars for me each year, I give them a set price for cars and another for SUVs that include a full interior detail and a two step (light claying only) exterior detail. Any trashed interiors or finishes that really need more than two steps to bring back have two options. I do the $$$ amount of work on the car I am being paid for or the employee pays the difference. Only a few of the cars I have done there have been really bad and in all cases, no one wanted to pay extra. Anyway.....
This is parked outside, under a pecan tree, as you can see in these before shots:
That is a mixture of pecan shells and rock chips on the hood.
An Optimum No Rinse wash cleaned it up nicely but revealed some bird bomb etching, light rotary swirls, halo swirls, etc. I tried to capture the defects as best as I could in the bright sun. If you look close, I believe you can see some light horizontal rotary swirls on the trunk lid and verticle ones on the first hood shot. The headlights are horribly oxidized and only wetsanding is going to fix them. I didn't have any sandpaper with me and the owner of the car (the boss's son) is heading back to college this weekend so they said they might have me come out and take care of it and detail it again during Christmas break.
I used my new Ultimate Detailing Machine on this car in conjunction with an orange Sonus Swirlbuster pad and Optimum Polish. I spread the polish out with the speed on 4.5 and then cranked it up to 6. First thing I noticed is that the sound isn't as shrill as the Porter Cable. Second thing I noticed was it still spins at pressures that only allow the PC to oscillate. Number three was that is removes paint transfers a lot more quickly. The combination of the UDM, Swirlbuster pad and Optimum Polish did a pretty good job on the vast majority of the defects. Some of the deep bird bomb etchings and scratches remained though.
This is after polishing only...
