That I wouldn't doubt. I have a bottle of Cabelas tumble polish and it smell a lot like auto polish.
After looking at the tumble polish it is not at all like auto polish. I could see using car wax/polish for tumbling could be bad juju. It might leave a layer of polish or wax on the shells that would make them slick. They may then not grip the sides of the chamber walls very well and put a lot of pressure on the bolt. This could lead to a major failure.
