This Jeep will be heading to the sand blaster, but that process will not take off the rubberized undercoating and spray-on bedliner. Jasco paint remover worked well to remove the undercoating on the bottom of the tub and firewall, as well as the spray-on bedliner on the interior of the tub. It is a labor-intensive process. The chemicals loosen the unwanted material from the steel, and some work with a scraper gets the job done. In this case, it took several sessions of remover solution, soak time, and scraping to get it to a usable state.
