First I did what jimig1 recommended to take them off with the duck tape. I then put a splash of water in them and sprayed a tad of bright orange paint in them. Shook it around a bit with the water in em. Then poured it out and let it dry in the sun. Came out nice. Think any tint paint would be good as I did not have any, so I mixed with water. So it would dry as a tint and not a thick paint covering. Think they would look nice in light blue too.. Tinting them is much better than that white. Km
