Funny thing is that I live on a busy street, I was just waiting for some enviro Nazi to stop by and read me the riot act (no worries, I'm well armed! ). It really doesn't make that big a mess, the undercoating disentigrates and looks like muddy water, it sits right under the car and scoops right up, and lucky for me I just happen to have a steam cleaner to clean off any remaining small stuff in the driveway, looks as good as new and nothing went into the gutter, my lawn boarder soaked it right up.
