Hello from Nor. California!
Thought I would go ahead and "finally" get involved here and make a post.
I'm pretty new to the detailing world, having only worked on a handful of cars for friends. I purchased my Porter Cable DA and Menzerna product line probably 5 years ago now, and enjoy the transformation process of detailing.
After reading and seeing what some of the experts are doing here, it's obvious I have a lot to learn!

Looking forward to learning from all y'all and practicing more!
Here are some pics of a car that I detailed last year. It's a black Infiniti G37.
I actually charged a small fee for this one...but it was my first Black car.
Ok...here are some "Before" pics. The lighting isn't the best for the pics...but gives a pretty good idea.
Notice the defect in this next picture...was in the section just above the driver's side door. "Scratch" was somehow in the clear coat...not sure what somebody did to get it there.
Ok...now for a summary on the detailing steps and products used.
Obviously washed it...just used Meguire's Gold car wash.
I Clayed the car using the Pad you can use on DA Polishers with Blackfire Clay.
Then proceeded with Menzerna's Super Intensive Polish using a Lake Country Orange pad.
I then used Menzerna's Final Polish II with a LC White Pad
The final step was a few coats of Blackfire Wet Diamond with a LC Councours Finishing Pad. Voila!
Given this was my first black car, and probably 5th exterior detailing effort total I was happy with the outcome.
Remember that horrible defect with the word "scratch"?
This is a picture of that same area. (This is my favorite Pic...you can't even tell it's a picture of a car or paint...pure reflection)
Thanks for looking!
