Maybe someone on here is a body man with the answer. Is there any auto body filler currently available that does not include talc for the filler portion?

I've googled and searched the web and every product that I've found mentioned in a thread that uses microspheres instead of talc still contains 20-50% talc when I look at the SDS.

I've looked at Evercoat light weight and Everglass, USC Duraglass, and even some of the metal fillers and they still show talc in the ingredients.
