Anyone else used this stuff? Expensive? Yes. Worth it? Worth every single penny!!! I put it on my truck in about 45 minutes or so. Covered everything but wheels and tires. It stayed clean a full seven days without washing, and only using a duster to get my gravel driveway dust off it. It would have gone longer I'm thinking, but the weather went bad. Nothing can compete with that lol. Anyway, seven days still clean? On a black truck? Awesome!!
