That moment I realized I was parking my coupe on the wrong surface
I kept noticing rust spots on the undercarriage of my '72 Datsun 240Z every spring, even though I stored it in my garage in Dayton. After 5 years of this, my neighbor Bob who restores Mustangs asked if I was parking on bare concrete. Turns out concrete sweats moisture up from the ground, and I'd been trapping it under the car all that time. He convinced me to lay down a layer of plastic sheeting and then a carpet remnant on top before parking it. Anyone else find out the hard way that concrete isn't the best for long term storage?
