I tried searching and read through all the write ups I could find about wet sanding headlights but I have one last question that remains unanswered. I wet sanded the lights on my buddie's Grand Cherokee a couple years ago but I can't remember, when switching from one grit sand paper to the next do you alternate the direction of your strokes? For instance if I'm using 800 grit and sanding from side to side, when going to 1200 or whatever should I go up and down? Or does it not matter at all and I'm just crazy?:clap:
