I hired a professional detailer about 3 years ago to clay bar over spray on my bus he intriduced me to TECH-SHINE, it all I use now. I keep it on my Caddy CTS V which I show every once in a while and the wife's car and the bus.......all have impeccable finishes. I used exclusively Maguireās Professional products, but now I only use Meguires for polishing / compounding damaged surfaces and TECH-SHINE for day to day maintenance. TECH-SHINE has been developed and used for years in boat racing and high end Air Craft exteriors.........It great stuff give it a try!
