Well, like I said, it was a thought and I was just wondering if it was a good one. Apparently not. I already know it's not asbestos, so no worries there. Part of the problem is that the popcorn has been painted over. I did have a guy tell me it does matter one way or the other. He said the difficulty of the job lies in whether the ceiling was primed first or not. If not, it comes off really easy. I plan to test a few spots to find out.
