I smeared my paper cone edges and I can say that the coating really sturdy and it seems to me powerful and truly effective for a longer time.

Foam Guard is like a vitamin for your speakers
As a life long audiophile, and a college physics teacher, I want to endorse the MI-1291FG Speaker Cone Edge Sealer. I have four 15" subwoofers that have served me well for more than 15 years. The edges have begun to appear dry, weak, and two even had small tears. I followed the directions precisely (and recommend you do that too, and they are well written) and 24 to 36 hours later they were totally dry to the touch. The two tears were totally mended, and the speakers work perfectly now. Yes, I drive the bass drivers hard, sometimes. And they continue now as though there were brand new. I endorse this for ALL audiophiles, of all ages, and all sizes of speakers.
