When I stripped my 230SL several years ago, I used a dry stripper. Don't recall the brand name, but there were a few different ones on the market that worked the same way. They were brushed and you waited until the finish bubbled up into a dry mass that you simply peeled off. It was one heck of a lot less messy than the wet strippers that are commonly used and just as effective. I tried the so called"safety stripper" as well and it just didn't work very well.
