Astroshield is the best polish I have ever used. I have been using Astroshield for 35 years. I have tried other products on the market, but have not found one that could match the polishing and durability that Astroshield offers. I have used Astroshield on both motor vehicles and aircraft. Astroshield gives the paint finish a wet look, and is incredible in removing light scratches from plexi-glass aircraft windshields. I also use Astroshield on my camper-trailer. It removes stains in the fiberglass shell and gives the trailer a new look that lasts for months.

polish 而且瓶上有強調不是蠟，以及他說有去除壓克力細紋的效果，再參考一些老文，我覺得他是研磨成分+不是蠟的保護成分(油脂類?)。
sorry，我沒趕上那個時代。
