First you need a new windshield. Urethane, spatula, hammer, gasoline, some old fabric and a helper.
1.- Remove the windshield wipers and the grill that covers the bottom of the windshield, you will see the 2 plastic bases where the windshield stands.
2.- Remove the plastic surround side and top mouldings, do it gently since the plastic can be old, you're going to use it again.
Step 1: Glass Detachment
Separate the glass from the urethane, since the urethane is very strong, use a hammer and a spatula (this need to be done gently since you don't want to damage the paint)
This is where the helper is needed because he is going to tell you when to stop, when he sees the spatula blade out, he's also going to tell you where is not finished.
Step 2: Take Out the Glass
Since this windshield is laminated it won't brake in pieces, remove the glass and clean the old urethane with the spatula, do it gently. Use some gasoline to clean the surface. Watch for any imperfections.
With a sharp knife remove the mirror and clean the base with the same knife, you may need some sandpaper and gasoline to clean it well.
Step 3: Mirror
Attach the old mirror on the black spot of the new windshield. Clean both surfaces well . Use epoxy glue, it will take 10-20 minutes to dry.
Clean the surface with gasoline / Attach the plastic moulding . Use packing tape to help.
Step 4: Clean and Glue
Using a pistol, glue the frame with urethane, use enough urethane so you won't have leaks
Step 5: Done
Place the windshield beginning from the top, then make it rest on the 2 plastic chucks, let it dry for at least 4 hours before driving the car.
Reattach the plastic grill and the washers.
Remove the tape
Now you have a new windshield and you can tell your friends about it.
