Attached Garage Storage Question

[Mr70]

Me too.
Two of those laid end to end,with a plastic vapor barrier under em,then a piece of carpeting ontop of all that.
I then jack the car up and place an additional 24X11X1-1/2" thick piece of wood under each tire to prevent anyother moisture from reaching the tires.
DON'T COVER YOUR CAR! Let it breathe..
Leave the Hood & trunk wide open too,to let any condensation that might sweat in,evaporate out quickly.
Set industrial size DRYPAC bags on the floor and seats of the interior too.
Unplug the automatic garage door,(make sure it's sealed),motor until spring as the door should remain shut until then.
For 23 years this has kept me from needing a controlled climate garage or lift and eliminated any major spring de-oxidizing knuckle busting undercarriage clean up.
It works for me..
