The Fiero sits rather low to the ground. This low center of gravity gives the Fiero excellent handling, but also makes it prone to a lot of stone chips. These tiny cracks can quickly spread, and when they get to be larger than an inch in length, you need to replace the windshield or you risk the entire windshield shattering. Once the windshield has been removed, installing a windshield on a Pontiac Fiero is fairly straightforward. However, make sure that you follow a specific procedure so that the glass will properly adhere to the frame.
Clear away any residual urethane on the windshield window frame. Cut the old urethane down to approximately 3 mm.2
Clean the pinch weld area on the sides of the frame with a brush. Make sure that there is no remaining debris.3
Coat the frit band with urethane primer. The frit band is the black edging on the glass. The primer opens the pores on the frit band and allows it to adhere to the urethane.4
Run a thick bead of urethane around the perimeter of the frame where the windshield will go. Use the 3 mm of remaining urethane as a guide.5
Align the top, bottom and sides of the windshield on the Fiero's frame and press the windshield into place. Allow the urethane to cure for at least 12 hours.
