DeLorean vehicles, with their iconic gullwing doors and stainless-steel bodywork, utilize a flat, wide windshield that plays a central role in the car's futuristic design. In cold climates, the broad surface area is highly susceptible to frost and requires gentle heating to avoid cracking, particularly given the age of most surviving models. Defroster systems are often underpowered in original configurations, so aftermarket upgrades may be necessary to avoid glass stress. In warm climates, UV rays can deteriorate older adhesives and dry out seals, which can lead to windshield lift or leaks. Since many DeLoreans still use original rubber components, these are particularly prone to shrinking and hardening under sun exposure. In humid environments, poor seal performance can cause interior fogging, water ingress, and mildew growth on the dash and trim. Owners should consider modern upgrades for seals, apply protective coatings, and avoid prolonged outdoor storage. Careful preservation ensures the windshield remains a functional and iconic part of this legendary design.
