Do, or don't? On my MX-5 I did hand washes due to the top, but now I have a solid roof car, so what is the verdict on using these? Touchless only? or are the ones with brushes okay to use? I don't wanna be an idiot, and I can certainly hand wash my car just curious as it would be easier to take it through a wash. I know since I've joined I've asked a ton of questions, but I figure the more I know the better off. Not only that, others may have the question and are just not asking it
