Been out of the shop 5 years, on my rare visits back have noticed more 3/8 ratchets, impact tools, drills of the battery variety, 5-6 chargers lined up on bench tops. Even 1/2 impacts are mostly electric. Trouble lights are cordless, air tools in the transmission room, because they are metal which wipes off better than plastic, every bay has air, with a regulator. The body shop is still using more air due to the continuous rub of sanders. Personally have added a 1/2 dewalt impact, to my drill and 3/8 impact, all in 20 volt. Short usage out away from the air hose.
