You don't really need to do your whole car with Aquapel. Just the front windshield. It's most effective on the front because that's the way the wind blows against it as your driving. Unless you do a lot of backwards driving like Mater in Cars. j/k
Thanks, the Performance Auto Spa looks awesome. It's too far for me though. I now have bigger problems, my wife scraped the curb with the front pass. rim causing decent curb rash.
