I posted a thread here a couple months ago about some jagoff who was huffing aircraft stripper in a bathroom and died, and they wanted to ban aircraft stripper because of it. Well now almost all aircraft and paint strippers are going to a non methylene chloride formula, which sucks. The new "safe" formula takes closer to 45 minutes to work and still doesn't do as good of a job. It's also more expensive. And it smells terrible. Not like chemical terrible, more like rotten garbage terrible. I tried 5 auto parts store today and home Depot and no one had the original stuff. I found a pepboys that had some really old stock and they had a can. It was on the shelf so long the can was rusty but I bought it anyways. I was able to find the aerosol stuff at a couple stores but I prefer the quart and gallon cans.
