Okay, I have Car back and it doesn't smell of gasoline anymore!
I have applied the foam pipe insulation to the bottom of the airdam.
Should hold quite nicely, judging by the test I did before of gluing that foam to this sheet metal with Goop.
I'm trying to make turbulators, but the gorilla tape isn't easy to cut with the pinking shears I acquired. I don't know if they're dull or misaligned, or what. I tried putting it in the freezer for a bit thinking it would help make it more brittle, but it seems to have made it even more difficult to cut. I don't think I'm going to get a significant amount of it applied before the trip home (starting tomorrow morning around sunrise).
