It does a good job of holding the air dam to the same curvature as the bumper out at the ends, but I suspect the middle blows back. I'll be adding a couple of braces similar to what Kach22 did, except my stiffeners will by something 1/8 X 1 steel so that I can bend them back easily after contacting a snow band.

Looking at this picture reminds me of those wind tunnel tests of a box trailer and the air just swirls at the back, it may be doing so here in a similar fashion.
