Really nice work. So, I've been reading up on a few of these restoration threads. I have not seen how the artwork is removed. It appears that people just sand it off or do you use some kind of stripper to remove it? I'm used to working on arcade machines and usually you have to use a heat gun or stripper to take off the artwork. But from what I've seen here it sands right off. Is this correct? I will be restoring my first pinball machine soon. Figured I would do some homework.
