Plastic windshields are extremely durable and less susceptible to breaking than drinking glass windshields. Unlike glass windshields, the majority of plastic windshields are condom when put nether stress. But, finding a replacement plastic windshield can be hard. Fortunately, plastic tin can exist repaired with acrylic solvent cement and plastic buffing compounds.

Pace ane

Wash the windshield on both sides with dish washing detergent and hot water. Thoroughly clean the crack. Only use a 100-percent cotton wool rag for cleaning the windshield to avert scratching the polished surface. Dirt and grease can form a bulwark that impedes the solvent cement from fusing the broken plastic. A crack may go on to split up if not properly cemented.

Step 2

Tape the area effectually the crack with painter masking tape, leaving a ¼" border of exposed plastic around the cleft. Solvent cement can scar the finish of a plastic windshield if it spills onto the windshield surface. The record creates a bulwark between the windshield and the cement.

Step iii

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 peak. 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 procedure.

Step four

Use a thin dewdrop of cement downward the length of the crack on one side of the windshield. Capillary action will cause the cement to be pulled into the cleft. 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 effectually the crack. Apply a thin bead of cement, and permit 24 hours of drying time before proceeding to Footstep 5.

Apply a small-scale amount of buffing compound onto a 100-percent cotton fiber rag. Remove any remaining masking tape from around the crevice. Buff the area effectually the crack until any residual cement has been polished abroad. The buffing chemical compound contains an abrasive that grinds down the residual glue, while nevertheless leaving the plastic articulate. Wash the windshield once more, on both sides, with dish washing detergent. The project is complete.
