this has probally been mentioned before. but this product sure works good on our big trailer tow mirrors, & other truck plastics. here in buggy florida, it keeps the mirror fronts shiney, & easy to wipe the bugs off. I bought it for a sea eagle paddleski 435 that my wife, & I took to sugar loaf key, & had a ball with,not for serious kayakers, but fun to fish & paddle around on. I,m just a buyer of these products, & admire stuff that actually work. pat
