I recently bought a new 2018 Touring. (Very nice) My son is taking my 2015 Sport. When I was cleaning up the Sport I found a star type crack in the passenger side taillight. I suspect the lens is not replaceable by itself. No moisture inside. I would like to do a repair of some kind. My first thought is thin instant glue applied to the center of the star since that's the only place I feel roughness. I'm hoping that would wick in. Or maybe a smear of clear silicone. Most epoxy are not good with UV but there are some that resist it. Any thoughts? Would like to avoid a full replacement since I detect no moisture,
