Restoring the garage bay. Any garage ideas I should do to make life easier?

Looks like you are a prepper by the looks of your NOS bottles!
I have my own filling station, 21 bottles and 4 mother bottles that can be seen on the left side pic. At 2 bottles per pass in one car and 2 other cars with spray with 1 bottle each. It doesn't last as long as you think it would.
