2 days after we had this discussion and this is what the car looked like. Had a storm front hit the car while parked at work. It got covered in dirt and sprinkled with water. At least I got it to bead pretty nice! It sounds like I am better off just leaving it alone and worry about other things. I'll work on it in the Spring as it'll get all covered in salt and dirt through the winter anyway. Peacemaker, I used ONR on my last car exclusively. No marks what so ever. Used 2 bucket method and kept my washing sponge and dry rag clean by avoiding them touching anything other than the car paint.
