Thanks rjt65, the ink is the chemical that cleans the glass and yea your hands do get a little black from the ink.
For my detailing job I did this one all by hand, my arms felt like they where about to fall off. I just bought a PC polisher , I'm not going through that again! I've always had small cars and it wasn't that bad but this one is a little more than usual plus I'm not getting any younger.
This is what I do, again I say, I do.
Wash with a orange base car wash to get all oils and road grime off the car.
Clay bar it with Mothers using the car wash soapy water.
Polish with Meguiars. Each panel over and over until I'm satisfied.
Then two coats of Meguiars NXT. Two coats just to make sure I get the all the surfaces and of course the rims.
Clean windows with newspaper.
Polish the plastic lenses with Novus polish and Novus clean and shine.
Of course the usual terry towels, MF towels and MF sponge.
I'm not a professional detailer (or have OCD) by any means but this has always worked well for me.
