When was the last time you were driving your hot rod, miles from home, and it started to rain? Wipers will keep the windshield free from water, but not condensation. A handy roll of paper towels will clear things up, but two hands on the wheel are always better than one, especially in a hot rod in the rain.

Our solution at Ionia Hot Rod Shop was to build a defrost box. This '32 Ford five-window previously had A/C and heat, but no defrost; so, we thought it was as good a time as any to add this third layer of comfort while it was in the shop being "freshened up."

The heater had been purchased years ago sans the defrost option, and the center heat/air vent was not being used, so we decided we would route that vent to the windshield via some fabricated louvered vents. I think this procedure would be applicable to any early rod with a thin dash. It won't be strictly defrost, but it will be better than nothing.
