What's the deal with...

I believe damraider has a good product and hope to get a cap from him when I get some extra money but I think the stains that you see are from carelessness when people put gas in their car and pull the nozzle away. It always seems to drip a bit and after awhile, it accumulates into one large stain. A little care when filling up and wiping any spillage off immediately can go a long way. JMO Dennis
