Great idea. I would buy two right off the bat. Would like to see a dirty bucket after a good wash, fruits of my labor. Psychologically seeing the dirt in the bucket would give me more satisfaction of giving the car a wash and a job well done. It's all a mind game. Adam's new product design team needs to work on this, along with the windshield washer fluid. Don't want to use glass sealant on my windshield then to have it stripped away with the alcohol based washer fluid in the winter time.
