Cargo Cover - What is it worth?

[LunchboxCritter]

Anyone ever made anything out of synthetics and epoxy resins? I watched some videos and it really doesn't seem all that difficult. If you needed/wanted to use one, a vacuum pump (for bagging) would be about your biggest expense, next to the carbon fiber material.

There is also the risk of destroying the cover attempting to make the mold (I think you would have to remove the carpet to get a smooth surface). That is why I wonder what it's worth.

I really like it, and the only reason that I'm not using it is that my subwoofer box will not fit under it.
