I know this isn't exactly a super hypermiling mod but I could use some help.

At some point over the last couple of weeks my front passenger side wheel well arch fell off the car. This is the thing that blocks rain, mud and wind from whipping around in there. I don't know how it happened or when.

I am getting a very prominent wind/whistling/whooshing sound from that wheel well. I'd like to fill in the area but I don't want to fork over the $100 or so to replace it.

Can I use that cloroplast stuff that everyone always raves about? Would it hold up as a temporary replacement while I wait on some cash for the new one?
Does anyone have any experience with this?

It produces enough wind drag that the car pulls to the right while driving at speed and I know that my wheels are balanced and aligned.
