its a fairly easy process just takes time! just remove them and take out all your bulbs and the rubber thing around the main light, put it in the oven at 170-200 degrees for about 10-20 minutes. maybe do 10 minutes first and see if they'll pull apart. they should just pull apart but you can use a screwdriver to pry them but just be careful and dont use alot of force with the screw driver. the glue is way sticky so just try and keep it all cleaned up. then you just paint and when its all back together bake them again at the same temp to reseal the glue! now the glue may not settle even after its all done so you can put silicone around the lenses to be safe.
