Part #2 of 2
After marking the back of the aluminum panel, I began to fold it to the correct size and hammer it flat. The folds gave it extra strength, so I didn't bother trimming it down.
The finished product was exactly the right size to cover the area.
After a dry fit to make sure the size was correct, I pulled the panel back off and pre-drilled holes at the back of the panel. Then I re-fit it, and fastened the 4 screws into the back.
I then pre-drilled holes through the plastic from the bumper and aluminum panel, and attached the front screws.
Pretty happy to have the aero panel in place! The total cost of the project was once again zero, since I already had every bit of the materials laying around!
Total time was about an hour, start to finish.
Hopefully this willl help any of you guys who, like me, have an old Insight that has lost some of it's aero panels.
