Funny you should ask. Just this past weekend, I had to go to Home Depot to pick out a bunch of bathroom and kitchen supplies to be delivered to my home later on. I thought to myself, oh great...I'll be there for a couple of hours, and by the time I go back to my car, it'll have dings/scratches galore from folks in wagons and trucks opening their doors and scraping their supplies against my car. I park in a spot close to the entry/exit way, so that there are lots of people constantly passing my car. Well to my pleasant surprise, after a couple hours when I come out, I find there's absolutely no damage at all on my car. Yippee!!
So I throw some kitchen tiles I bought in my trunk, and drive home. Get home, and then while pulling out the tiles from my rear trunk, one falls on my rear spoiler, and scratches thru the clear coat. ARRGGGGHHH!!! Once inch scratch! I just can't win.
