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.
