Hey everyone, new to the forum and thought I would share. Six months ago I decided to try a Maquires "Ultimate Black" plastic renew product. I should have taken pictures of how bad they looked before, they were horrible, almost lighter than the silver paint. I applied the product per instructions and could not beleive the results! I thought to myself, looks great, how long will it hold up? The first application lasted about six weeks before I noticed any change, I applied it again and have not had to do so since. Take a look, they still look great!
