I've tried spray on/wipe off type products as boosters after washings since the days of Turtle Instant Zip Wax. These products came a long way since then. Aquawax, ONR used as a quick detailer, and E-1 Nano wax are 3 products that have all worked well for me. However, the one I liked best is a product I stumbled into called Simoniz One Step Instant Polish. I can no longer find it, and an e-mail to Simoniz's website was never answered. Did anyone else find this best kept secret product, or know what ever happened to it?
