i put 2 coats of finish paint on. it dries rather quickly and all this can be done in one afternoon. once done painting, let it sit for atleast a day for the paint to dry thoroughly and prevent you from messing it up in the mean time
on these, i powered via a 9v battery that was latched to the top of the overland chassis. it included a slide switch so i could turn the light on and off. from the outside of the truck.
