Reproduction tail lights - how to get them made?

I saw a car show where they made some lenses using a latex mold and formed one from a good used one. Not sure of the specifics but they formed it with a red plastic and polished it after and it looked good on TV.



unrelated to tv show but youtube on how to do it.


I found Smooth-On easily. Looks like just the thing. But, way more of a project in itself than I had in mind. I am thinking of who would do that for me. Thanks.
