We have been formulating cleaning chemicals for years, trying to make ones with better results at reasonable cost. For many years, we have only sold products to the automotive detailing community. About 5 years ago we began selling our products at small airshows and been asked if we had a good metal polish. So I began the long process of research and development. In those 5 years we tested and reformulated these products until the current 3 were developed. We gave out samples to a small test group to compare against others in a blind test and the results proved we had the easiest to use, with the deepest shine. After many years of development we come up with a product that I am truly happy with. But before it could use it on aircraft it needed it to be to be “Aviation Approved”, so we had it tested.
