I tried to remove it one time and nothing, finally I took it to a powder coater and they used heat in the process. I think they hot it hot in the baking oven and then blasted, or scraped it off.
A large operation would do it that way. Some also have tanks of some really wicked stuff. When we raced Karts we'd have them re-done every year. But sometimes what you want to do isn't worth the time a fuel to take your stuff to one of those shops and then go back a couple days later to pick up, not to mention the cost.. The gasket remover works awesome for the backyard job !!
