I am a 56 year old owner, collector, restorer and builder of American, British and European Cars and Motorcycles. Over the last 30 years I have used about every car care and motorcycle detail product known to mankind. I can state without hesitation the products which I buy from The Detail King are the best on the market. I state this both in terms of applying the various products but also in regards to how long the products provide shine and protection to my cars and motorcycles. Keep up the good work!!
