stipping paint??

[monkers]

Im looking for a way to remove the paint from the sheetmetal parts for my Jonhson Model B saw. I dont want to rip into them with a wire brush, and I couldnt get the inside of the shrouds anyway. Then I was thinking someone with a sand/bead blaster?? WIll this hurt the sheet metal? Also, I live in a small town, so Im not certain there is anyone around here that will do it (have one guy I can ask). The rest of the saw I can use the wire brush on the 4" grinder or something similar.
There are numerous coats, some peeling, so it should all come off. I have no experience with chemical strippers at all. Someone told me to try Oven Cleaner. Any info would be appreciated ......thank you
