Reviews

"Product seems to do as they say. Car looks great inside and out. I live on a dirt road. It's one mile drive on dirt to get to asphalt . I like my vehicles looking clean. I've only have had it on for a couple weeks and I am amazed on the tire product on how clean my tires are staying. I'll come back in a few months with pictures and give a review. I'm using nothing but Top coat products for panit,windows and tires. Living on a dirt road is a challenge for someone who wants a clean looking car. This will be a real test."
