Windshield stars can very allot in size and design. Some have small bulls-eyes to them such as the samples here. Some are all legs with no bulls-eye. Most Stars need to be drilled to make a better path for the resin to flow into. Drilling helps the stars legs fill better and speeds up the repair. There are two ways to drill. One is to drill down to the plastic. The other is to drill part way down to the plastic usually about half way to the plastic and tap a bulls-eye. If you are unsure of how deep to drill or only have a basic kit with out a taper drill to the plastic. Go easy on the pressure with your drill so you do not break off the tip of the drill bit as you break into to plastic layer in the middle of the windshield.

If you choose to drill and tap drill part way down to the plastic and use a taper and a probe to tap a bulls-eye. It only takes a very small tap to connect the legs of the star and improve the path for the resin to flow.

Screw suction cups on to Crack Easer tool. The suctions cups go on the non ribbed side of the tool where you see word Crack Eraser.  Lube suction cups with lubricant.

  To mount the crack eraser tool set the tool with the bigger threaded part over the chip you are going to repair. It usually works better if you mount the tool above or below the repair not to the side of it unless the chip is close to the edge then mount to the side. Push firmly down on all three suction cups until you do not here a squishing sound. It is important you push hard enough to get all the air out the suction cups or the tool may pop off during the repair.

Install Injector O Ring on the Piston and push into the injector do not tread in yet. Next tread injector into the crack eraser tool. Then tread adjusting bolt into crack eraser tool. 

Adjust the injector and adjusting bolt by turning each of the in until they touch the windshield the turn 3 turns more on both the injector and the adjusting bolt. You want the Crack Eraser tool to be level with some pressure on the injector so you can keep a seal while injecting. 

Add 5 drops of chip repair resin to injector. If the Crack Eraser tool is being used for the first time you will need to add 5 drops of chip resin to the injector. If the tool has been used for another chip it will still have some resin left in the injector so 3 drops will be enough resin to a chip repair.
