This is the stuff I use. It’s taken off paint, varnish, and the factory finishes off a T/C, my Investarms Bridger, an India-made fusil de chasse, a painted wooden chest, and a few tool handles. I’ve used it indoors, though I recommend the porch. I let it sit for a few hours or overnight, scrape away the goo with a plastic palette knife or one of those fake credit cards they send in the mail, and wipe down with a damp paper towel to finish the job.
I probably have something laying around that I could strip if y’all think a documentary thread would be helpful.
