I saw a product on a tv show the other day that was sprayed on and wiped off . It was used to fill in and cover small scratches on a car's hood. Didn't actually show how well it covered it though Does anybody have a favorite product they'd suggest to try? I've seen numerous products at the auto parts store(one even had like a pencil thing you rub into the scratch) that claim to do this and remove swirl scratches. Thanks for your suggestions.
