Instead of being laminated glass, some windshields are created with a more durable transparent acrylic compound commonly known as Plexiglas. It will not shatter like a typical glass windshield and is therefore used in cars used for racing or activities such as off-road driving. Although it is a strong material, Plexiglas can still crack if it encounters too much applied pressure or extreme impact. However, a crack in the acrylic windshield can be repaired in a few steps.
- Make a hole in each end of the crack. This will prevent the crack from spreading.
- Fill the crack with Plexiglas / acrylic glass glue. This is a very thin solution that can drip, so have a rag handy to clean the solution that overflows the crack. Allow the solution to dry for the recommended amount of time as indicated on the acrylic glass adhesive package.
- Buff the surface. Use an electric polisher and soft polish pads to do this.
- Clean surface. Use the Plexiglas / acrylic glass cleaner and the remaining soft cloth to do this.
