Hi Chloe, The best option will be to take your vehicle to a local and reputable auto glass shop. Hi Jerry, It is likely a coincidence that you are just now noticing these chips after the sunroof installation. Twitter Facebook-f Linkedin-in Houzz Instagram.
This pulls a partial vacuum in the syringe—and in the crack. While you're holding this vacuum, the air in the crack bubbles up through the adhesive in the syringe, while adhesive creeps down toward the glass and chip. Now let go of the handle. Don't follow the handle, but let it go abruptly. The pressure wave from the handle slamming down will force adhesive into the crack. Repeat this suck-and-slam operation a half-dozen times or so, forcing the crack virtually full of adhesive.
Now remove the syringe, adapter, and adhesive sheet. There will be a film of adhesive on the surface of the glass. You can chase that back with an alcohol-dampened paper towel, but leave the pimple of adhesive right above the crack undisturbed until it cures for a few hours.
With the pimple hardened, simply take a single-edge razor blade and shave the protruding adhesive off. Use a sharp blade, and you'll be able to do this in a single pass. We also tried a repair kit that used a two-part adhesive. These are far less common—though you might find them in your search and be forced to use one in a pinch—and they require users to mix two small vials of adhesive and hardener in the syringe before starting, which was simple.
The adhesive disc and syringe adapter are similar, if not identical, to the simpler kit's, and are applied in an identical fashion. The syringe, however, is more complex.
It uses a wire latch arrangement on the body that drops into two notches on the handle when necessary. A simple pushpin stuck into the body serves as a very crude valve to let air in and out of the body.
Once the syringe is attached to the adapter the adapter already being stuck airtight to the glass , you remove the pushpin. Then you bottom the syringe plunger, pushing the air out, insert the pin, and pull the handle out until the clip clicks into the slot.
This will hold the plunger out, and the partial vacuum under it for the designated time. Rather than rapidly releasing the pressure like you do with the Loctite kit, in this case you remove the pin, admitting air into the syringe barrel.
Then you replace the pin, sealing the hole, followed by releasing the clip, pushing the handle in to lightly pressurize the barrel and force adhesive into the chip for a minute or so. The second slot will trap the clip as soon as you've pushed in far enough. Repeat this "vent, suck, vent, squeeze" operation several times to force adhesive into the crack.
While the clip-and-slot and vent system relieves you of the necessity of constantly grasping the syringe barrel like it's the last beer at the picnic, there are caveats. The vacuum pulled isn't as good, purging less air on every iteration. And the simpler Loctite kit seemed to force the adhesive deeper into the crack faster by using the plunger as a piston to rapidly pressurize the system. Having said that, both kits did a great job.
