The full review

Why the body shop won't tell you this

Stop paying $400 for a windshield replacement when the crack is under six inches. Body shops don't mention it because it's not their margin, but a $15 DIY resin kit fixes most chips and cracks if you do it within a few days of the damage.

The resin goes in a bridge tool, a UV strip cures it in about 15 minutes of sun, and a razor scrapes the excess. Done. Wait too long, though, and the crack spreads past the fixable point, then you actually do need a replacement.

What I liked

  • A fraction of a replacement cost
  • Cures in ~15 minutes of sunlight
  • Bridge tool makes it foolproof
  • Stops the crack from spreading

What to know

  • Only for chips/cracks under ~6 inches
  • Must be done within a few days
  • Doesn't make damage invisible
  • One-use resin per kit

Common questions

How big a crack can it fix?

Roughly under six inches, and the sooner you do it after the damage, the better it holds.

Will it make the crack invisible?

No, it stops the spread and greatly reduces the appearance, but you may still see a faint mark.
