Thanks to everyone who has responded. Great info.

Dennis, link inside the post you sent doesn't work. All there is is a Wikipedia explanation as to the compound of the material. I had already found that one through the search.

Plus it doesn't hurt to get some new articles going. Some people might have found new/better products than in 2011. Search function is great but not the end all be all or else we might as well shut the forum down as most things have been discussed at least once.
