Kevin, how is that paint holding up to warm/hot tire rubber when you drive in on it? We went to Menards last night and got brochures on a couple of different floor paints. The guy there told me to etch the concrete prior to use. Since your floor was already painted, I assume it had already been etched once. Did you remove all the old paint or just paint over the old? My floor won't get paint for at least 6-8 months, but it's never to early to ask and learn.
In a while, Chet.
