Actually here, your wrong, the moisture wicks up through the concrete, even if you have double vapor barriers when the floor was originally poured. With just the addition of the rubber mat underneath my show cars, I eliminated the need to redetail the undercarriage after a winter sleep............The only reason to add a dehumidifier now is to keep the rest of the car just like the undercarriage...

Rather than moisture coming up through the concrete, I'd bet most of the moisture problem on garage floors is condensation caused by the concrete being colder than the dewpoint temperature of the air. This being the case, no coating is going to solve the problem unless it is a pretty good insulator, like Bill's big rubber mat.
