After the primer was applied and allowed to dry, 2 coats of Gloss Black was put on and in 30minutes I was handling the box and putting the rocker switches on. The grey ones were drilled out to accommodate the 2 LEDs I purchased. Wiring was then soldered to the terminals and the switches glued into position. The wires were then connected to the switch and power supply,which is 2 x AAA batteries in a holder.
