Personally, I think the mesh will look exactly like what it is -- a cheap and quick cover-up. This will not enhance the appearance or value of your Boxster, IMO.

If you're going to go to the trouble, why not do it right? You should be able to find a shop to make you a plate that will fit across the whole space, or do it yourself with some simple tools -- a bandsaw or hacksaw and a file. Paint it body color, or black, and it will look professional and finished.

I remember seeing this done somewhere, probably here on the forum, but I can't give you a link.
