North Hampton, New Hampshire, October 16, 2026 - Committed Collision & Auto Body Center, an I-CAR Gold Class collision repair facility in North Hampton, New Hampshire, is helping area drivers understand why aluminum and steel body panels require different repair methods. As more manufacturers build aluminum-bodied vehicles alongside traditional steel models, the shop said knowing the difference affects safety, warranty coverage, and quality of auto body repair after a collision.

Why Do Aluminum and Steel Need Different Repair Methods?

The two metals behave differently once a vehicle is damaged. Steel can typically be welded and reshaped with standard equipment shared across a repair bay. However, aluminum reacts differently under stress and can pick up contamination from tools previously used on steel. Left unaddressed, that contact between metals triggers galvanic corrosion, a reaction between dissimilar metals that continues to spread beneath a repaired panel over time.

Guidance published through I-CAR calls for facilities working on aluminum to maintain a dedicated set of tools, from sanding equipment to dent-repair tools, that never touch steel. Despite aluminum's growing role in vehicle construction, a study by P&L Consultants found that aluminum-bodied vehicles account for less than 1 percent of collision repairs nationwide. The company said that gap leaves many facilities with limited hands-on experience in aluminum-specific procedures.

"A lot of drivers do not realize their vehicle has aluminum panels until something goes wrong with the repair," said Derek Lighthall, owner of Committed Collision & Auto Body Center. "The tools that work fine on steel can actually damage aluminum if they are not kept separate."

Why Does This Matter for Vehicles Repaired in New Hampshire?

New Hampshire road crews apply an estimated 400,000 tons of road salt each winter, according to the Northeast Interstate Water Pollution Control Commission and the New Hampshire Department of Environmental Services. That level of road salt, combined with moisture and metal contamination, raises the risk of long-term corrosion on repaired panels. The shop said this makes proper material separation especially relevant for vehicles repaired in the region.

What Should Drivers Ask For in an Auto Body Repair Estimate?

The company recommends that drivers request auto body repair estimates specifying whether a vehicle's panels are aluminum, steel, or a mixture of both. A proper estimate should also confirm that the shop keeps separate certified tools for each material and that structural repairs will be measured against factory specifications rather than general repair guidelines.

What Equipment Is Used for Auto Body Paint and Repair?

The shop uses equipment such as the Chief 3D Laser Measuring System and Spanesi Touch Measuring System to confirm that structural repairs meet factory specifications, along with dedicated tools for aluminum panels. For auto body paint and repair, technicians match a vehicle's original factory color using Glasurit 100 Line waterborne paint, used by over 80% of OEM manufacturers.

"Our goal is to give every customer a repair that meets the same standard the vehicle left the factory with, whether that means steel or aluminum," Lighthall said. "That starts with using the right equipment for the right material and explaining the difference to the customer."

What's Next for Drivers Who Need Auto Body Repair?

The company has served the New Hampshire Seacoast since 2005 and holds I-CAR Gold Class certification, a shop-level designation recognizing training in current collision repair standards, including aluminum repair. As more manufacturers add aluminum-bodied models to their lineups, the company said understanding these repair differences will matter for more drivers weighing their options after an accident.
