Garage floor advice

I did not epoxy my garage floor ... Key is to NOT open garage door IF possible , when raining ,,, or drastic change in temp .. which can cause garage floor as well as vehicle itself accumulate moisture ... Let the inside garage air change gradually on its own between seasons , with doors closed ....
Instead of using expensive epoxy paints .. you can purchase a cement sealer .... make sure you get the one that seeps into cement and NOT the one that sits on top and creates a surface coat ... purchase this product at a specific concrete/cement supply store .
