I have found that the small soda blaster that Harbor freight sells is a good tool to have avalible for small delicate parts. I use to refinish wood and found it worked great for that and then started striping paint on motorcycles with it. It will not harm glass or chrome, its a bit messy but very safe heck you can eat the stuff. Its just an idea that might help somone I think they run around 100 bucks but it is a heck of a tool..
