Does Simoniz Liquid Diamond Really Work?

Simoniz Liquid Diamond is car polish that claims to apply the perfect polish to bring out the best in automobile coating. The product itself is designed to provide long lasting effects when applied on a car whether wet or day. Users apply the product in liquid using a battery operated sprayer with pistol grip. There is no need for buffing or hard rubbing once the product is applied using the sprayer. The product is also said to be easy to use (with an instruction set) and can also be applied on the windows, windshield, bumper, side-mirrors in addition to the main body.

Bought it and let it sit inside for a year. Just used it on my car and realy liked the motorized pump, BUT after rubbing and letting it dry the car looked no different, same dull oxidized paint.

My father let me use the Simoniz on my Black 09 Mustang. Boy do I get the Thumbs up after I wax my car. And before I go out I use the spray wax, I recommend it to all my friends

I have a Corvette and a 08 Mustang,Candy Apple Red. Liquid Simoniz is the best polish I ever used in 42 years of waxing cars. And the Simoniz spray wax withe the battery operated spray is the best. Ever friday I used the Simoniz,sat. morning I use the spray and it’s the best shine you will ever see. I bought it last year from Billy Mays infomerical now I buy it from my local car wash. My son also loves it on his Black Mustang
