This may be a dumb idea, but does anyone think it would work to get similar paint in bottle or small can, and use an eye dropper to drop the red or red/smoke mix through the reverse light hole, and just tilt the light till the paint runs over the inside of the clear lens? You would have to be careful to thin it out enough to make it a light coat, not overfill unless you can remove the excess with the eyedropper, and not tilt it so much that you get any on the reverse reflector, or anywhere else you don't want it to be. The benefits being that you won't need multiple coats, sanding, or clear and you will still be completely glossy on the outside, and the paint shouldn't weather, and there is no need to cut them open (unless you really screw up.
