Review on Black Again Exterior Trim Detailer - 8 oz. by Blue Magic - Enhanced SEO by Greg Birchfield

Two things you need to know about this product: 1. It is not permanent - you will need to reapply. And depending on how exposed your car is to the elements, it could be a month or three months; and 2. If you have very bright sunspots on fenders, bumpers, etc., this can exacerbate the blackness around them and make it worse. That being said, this product does exactly what it says on the tin. I used it for my Jeep's fenders and bumpers. It wasn't garaged for the first few years that I owned my Jeep, so it had some faded sunspots on the fenders that turned everything dark black so they were more noticeable. But it was really easy to apply and overall everything looked shiny and new. Love the product - just think people should know what to expect!
