Well, I took my first run at using iron-X and hope I did it right. Washed the car and dried it then I sprayed it down with Iron-X. While it was still wet I spread it around with a damp, not wet grout sponge. When I did this it produced a white film. I let this sit for about 5 minutes and then rinced off. I was expecting to see little spots of rust disolving but didn't see any that stood out HOWEVER when I rinsed the car the water running on the driveway was a very rusty color. SO...I guess it did it's thing? Afterward I could still feel some rough bumps here and there so I guess Iron-X doesn't get it all. Was planning on going over the car with clay before polishing. Does this sound like things went as they should have?
