I saw this product on an infomercial late one night in the mid '80s (back then it was called Pete Nathan's Liquid Luster). I used it on my corvette at the time and the shine was better than anything I had ever used. I just waxed up my STI with it on Saturday morning. My baby is satin pearl metallic and I must say that Liquid Luster does an outstanding job. Easy on, easy off. What do you guys think of this stuff?
