This post is the ninth in a series on the basics of auto glass, auto glass repair, and mobile windshield replacement. If you haven’t read parts 1-8 yet, I recommend you do before continuing.

What is the Safe Drive Away Time (SDAT) or Minimum Drive Away Time (MDAT)? (continued)

MDAT is a term that is gaining ground in the industry, but both MDAT and SDAT mean essentially the same thing. If the company tells you that you can drive your vehicle immediately after the technician is finished, call another company. There’s no such thing as a windshield replacement that doesn’t have a SDAT, and anyone that says there is isn’t doing it right.

Ask about materials they use

The goal in a windshield replacement is to replicate original factory conditions as closely as possible. With this goal in mind, it’s important to use the OEM (original equipment manufacturer) replacement windshields, adhesives, and primers. Aftermarket alternatives are often cheaper, but they aren’t subjected to the rigorous engineering and testing standards that OEM parts are. This is true of replacement parts everywhere in your car, but it’s particularly important for windshields since they are so critical to crash safety. Chapman Auto Glass uses Essex Betaseal Advance Cure Auto Glass Adhesive. This adhesive costs 2-3 times as much as standard urethane, but does a much better job of replicating the factory windshield attachment. Other companies may use a cheaper adhesive to cut costs and give you a lower priced quote, but it will not stand up to the same standards.

Ask about what certifications they hold and what standards they follow

There is no cohesive licensing body for auto class replacers, so it’s up to the individual business to make sure their work meets the right standards and is up to snuff.
