How does the vacuum function work?

The applicator seals over the chip and draws air out of the crack, so the resin can flow in instead of being blocked. You then switch to the pressure side to force resin deeper.

Will it fix a long crack?

No. Kits like this are for small chips, star breaks and short cracks. A crack longer than a few inches, or one in the driver's view, needs a professional repair or a new windshield.

Do I need sunlight to cure the resin?

Yes. The clear curing strips hold resin in place while UV light from the sun hardens it. Park in direct sun for the recommended time; a UV lamp is not included.

The four-armed suction cup applicator, a small bottle of repair resin, several clear curing strips and a metal scraper blade.

Can I drive right after the repair?

Wait until the resin has cured and you have scraped off the excess. Avoid washing the glass or heavy pressure on the repaired spot for a day.
