How to Repair a Clamshell Chip in Windshield

A clamshell chip in a car windshield looks just as it sounds. A small shell like indentation in a windshield causes both limited vision and a distracting obstruction. Below are instructions on how to repair a clamshell chip using professional glazing equipment.

Instructions

1

Use a small drill tool such as the kind used in hobby work to shade in the interior of the clamshell chip. This is a soft circular motion to even out the indentation. The surface of the glass will feel rough to the touch when you are finished.

2

Apply a sufficient amount of resin into the indentation to an even level. Use a dabbing motion to avoid spilling out too much. This glass resin is available at department stores or online.

3

Apply a sufficient amount of pit resin over the top of the resin in Step 2.

4

Place the resin patch that comes with the resin over the top of the clamshell chip. Push it down gently to balance out all the resin and mixing the two types of resin together in the process.

5

Allow resin to cure (in accordance with the instructions on the back of the packet) before scraping off with a small clean razor blade. Be sure to push along and not into the glass as you remove the resin from the surface.

6

Wipe across the surface of the now smooth and level glass surface with a little window cleaner and a soft cloth. This should remove any remaining resin residue.

7

Polish the glass either by hand or with a polishing tool to finish off the repair.
