I never used to use tire dressing, but last fall I got a can of Megs Hot Shine aerosol spray. I like it fine, but I've only used it like three times and the can feels like I'm only going to get a couple more cars out of it, which seems ridiculous. So I'd like to know what to get that is more economical. I really don't care what type it is, gel, spray, whatever. Not really concerned that much with how shiny it is either.
