We built a homemade drying "oven" out of (2) 2 ft. x 4 ft x 6 ft chrome shelving units. They're held together with pipe clamps to create a 4 ft x 4 ft x 6 ft oven frame. Then, the entire thing (sides and top) are covered with 1" blue insulation board (to keep the heat in). The heat is supplied by a single infrared space heater with a fan on top, placed in the center of the "oven" on the floor. It Has temp settings and fan settings. This little heater creates enough hot air movement to keep condensation off of our lacquer between coats (even on humid or cold days) and makes our life a lot easier when combatting blush.
