AFAICT this is an adhesive overlay, and not a replacement. I would be very concerned about the look of the installed product and the durability. If you have ever installed a screensaver on a phone, you know how hard it can be to align things exactly. I personally wouldn't waste my money unless it was a solid material that actually replaced the existing material.
I actually thought about going the other way. Replacing the satin silver on my SL with a woodgrain overlay. But as Mattski says, there are a lot of little pieces that have to be installed, and I decided that I probably wouldn't get them all on straight and would end up with something that did not look like a factory install. So I saved my money and gave up on the idea.
