I have never tried it, When I bought this 66, the taillights looked great. The guy I got it from said he used "muggy weld"??? Almost like solder I guess. Sent them out for re chrome and they were great.
Just another option I guess.

Pot metal can be sanded, polished, and clear coated. You need a lot of thickness if you have a lot of pitts though. That is where the "Muggy Weld" comes in. To fill the pits so they can be chromed. I need to check on the Muggy Weld product. tmm
