Use the rotary polisher to buff and polish over the sealed crack. Place a foam buffer pad on the head of the polisher. Gently lay it flat against the crack, turn it on and use the lowest speed to start with until you get the hang of it. Move it in circular motions just enough to buff the sealed crack evenly against the rest of the Plexiglas windshield.
Drill a fine, tiny hole at the end of the crack. If the crack stretches across the windshield, go to the tip of its reach and drill the tiny hole. This will prevent the crack from extending farther across the windshield. Remember, the hole should be small enough to round out the end of the crack's arm, but not large enough to break the windshield.
Pour a small amount of Plexiglas cleaner on a soft rag, and go over the entire windshield for a clean, transparent finish.
Fill the crack with Plexiglas adhesive. The adhesive will be as thin as water, so be careful not to use too much pressure when injecting it into the crack using an adhesive gun or injector. You can find the adhesive at most hardware stores. Wipe away any excess adhesive that spills outside of the crack onto the windshield.
Car and boat windshields are often made of Plexiglas because it is an inexpensive and durable material. The biggest problem with Plexiglas is that if it cracks or scratches, the entire area around the crack or scratch becomes cloudy. Fixing a crack in the Plexiglas is the easiest thing to do yourself so you do not have to have a replacement windshield put in.
Tape the area around the crack with painter masking tape, leaving a ¼" border of exposed plastic around the crack. Solvent cement can scar the finish of a plastic windshield if it spills onto the windshield surface. The tape creates a barrier between the windshield and the cement. more
Apply a thin bead of cement down the length of the crack on one side of the windshield. Capillary action will cause the cement to be pulled into the crack. After the cement has dried for two hours, remove the masking tape. Apply masking tape around the crack on the other side of the windshield, leaving a ¼" boarder around the crack. Apply a thin bead of cement, and allow 24 hours of drying time before proceeding to Step 5. [links]
Plastic windshields are extremely durable and less susceptible to breaking than glass windshields. Unlike glass windshields, the majority of plastic windshields are safe when put under stress. But, finding a replacement plastic windshield can be difficult. Fortunately, plastic can be repaired with acrylic solvent cement and plastic buffing compounds.
Fill the applicator bottle halfway with solvent cement. Acrylic solvent cement works for nearly all transparent plastics. Using the thumb and index finger, apply pressure to the sides of the bottle until the liquid is near the bottle top. Slightly release the pressure. A vacuum has now been created within the bottle, keeping the cement from spilling when the bottle is tilted during the application process. here
