This one is by far the winner for dirt and grime. BY FAR. Belongs to the woman who lives above me. She is very busy and works the graveyard shift as an RN at Yale Hospital. She pretty much sleeps all day so not much time to care for the Jetta. This car stood out to me since I moved into my apartment 2 months ago. It looked battered. I spoke with this woman the day I did the Scotchbrite Maxima...She thought I repainted the car in the parking spot it looked so good. She explained to me how she spends winters in Northern New England (Mass, VT). She got stuck in a state of emergency (Snow Storm) and if she didn't move her car they'd tow her with a huge fine. She was already plowed in so her and her boyfriend went to town digging the Jetta out. Well, she took the steel shovel to her black finish :shocked . There were about 30-40 R.I.D.S. (Random Isolated Deep Scratches). After washing and claying, I took 1500 grit wetsanding papers and sanded the crater (indent) of the scratches. I then touched up x 2 (10 mins apart) with Audi touch up paint. Finally, I wetsanded with 2400 grit MicroMesh papers and compounded out with Menzerna PowerGloss via rotary and Cutting Pad @ 1700 rpm. Anyways, this was an exterior only job. It chewed up my clay bar and really needed a lot of work. Final processes were: -QEW x 2 -Wolfgang Clay on paint and windows -Rain-X to seal the glass -Meguiar's APC+ (10:1) to clean rims, tires, and wells -Touchup and wetsanding info above -Meguiar's #80 via rotary and polishing pad @ 1500 rpm -Menzerna MicroPolish via rotary and polishing pad @ 1500 rpm -Meguiar's NXT by hand -Meguiar's Hyper Dressing on tires, wells, and plastic trim Now for the pics Before After Before After I honestly don't think it's been washed in many many months. There was so much accumulated grime on the doors they were whiteish/greyish. Before After Here's what I'm talking about with the scratches. The big one was almost hopeless but I got it back to life pretty well. Before After Teh Wetness Shot 4 hours, $100 plus a 20 buck tip...I'm happy, she's happy...Life is good Enjoy!
