Versachem Windshield Repair Kit (90110) vs Permatex Windshield Repair Kit (09103)
Which should you buy? Our verdict on both, pulled from our full The Best Windshield Repair Kits: 4 Compared (and One to Skip) comparison.
Versachem publishes a timed vacuum and pressure sequence, a glass temperature window, and a cure time, which is the closest a shelf kit gets to the professional process. Permatex costs less effort to understand and is honest about the cosmetic result, which makes it the better first attempt on a simple bullseye.
Versachem Windshield Repair Kit (90110)
Buy itThe shelf kit with a real vacuum-then-pressure injector cycle, published timings and all.
- The injector locks in two positions, holding vacuum for at least ten minutes and then pressure for at least twenty, which is the air removal and resin displacement the repair standard calls for.
- The maker lists bullseyes, star damage and chips up to 1.25 inches in diameter rather than bullseyes alone.
- Instructions give a specific glass temperature window of 55 to 75 degrees F and a cure of at least 15 minutes in direct sun, or at least an hour on a cloudy day.
- One adhesive seal and one pedestal means it is realistically a single repair per kit.
- The full sequence takes the better part of an hour of standing around, and you cannot rush the vacuum stage.
- It ships one general purpose resin, so a tight crack and a wide bullseye get the same viscosity.
Permatex Windshield Repair Kit (09103)
Buy itThe straightforward bullseye kit, and the one whose maker tells you the blemish may not fully disappear.
- Contents are spelled out on the product page: syringe and plunger, 0.75 ml of repair compound, adhesive disc, pedestal, curing strip, push pin, razor blade and an alcohol towelette.
- Permatex states plainly that the repair may not completely remove the blemish or permanently fill the pit, which is the expectation most buyers get wrong.
- Clear working conditions are published: a shaded area with the windshield between 50 and 75 degrees F, then 15 minutes of bright sun or at least an hour of UV on a cloudy day.
- The product page describes bullseye damage up to 1.25 inches, so a sprawling star break is outside what the maker claims.
- A syringe plunger without a published timed vacuum stage gives you less control over trapped air than a locking injector.
- One adhesive disc, one pedestal and one curing strip means one repair.
