I've done a couple of these and the best way is to put them in the oven on 200 for 25 min. checking on them every 5 min to make sure nothing melts.Then with oven mits take em out and gently pry apart with small flathead screwdiver. Should pop off easily! Then tape off what you don't wanna paint, scuff w/sandpaper, apply 3-4 coats of paint.Let dry completely(at least 24 hrs) then apply clear silicone and put lights together applying firm pressure to both sides for a tight fit. let dry then put lights back in.. Hope this helps.
