Is there any way to remove bondo?

Besides sanding, grinding and scraping, you can remove Bondo from your clothes and other porous items with fingernail polish remover (acetone). Test the cloth in an inconspicuous spot before you try this because it will also dissolve some fabrics. You may need to let it soak for a while to soften it enough. Acetone evaporates very easily and is flammable so it would be best to do this outdoors. ZipStrip will also remove bondo but it is even more likely than acetone to destroy fabric...Test FIRST!
