Forget JAS** and paint strippers and all that other "must distill crap". DCM is as available to get as gasoline. I know I can't say exactly where to procure such an item, so i'll break it down instead. DCM is used in vinyl (flooring) installation as a seam sealer remover (glue remover). It is 100% or so pure, no toluene or other substances, only DCM, completely OTC. Its no secret where to find it, think of where you would go as a flooring installer to find a wholesale product, hint, some companies have accounts with such places, hint, they are usually located around industrial areas. Good luck, you won't need much though, its easier to get than you think.
