Your correspondent took his wife’s car to Dr. Ralph’s Automotive Services Center in Roxborough after she discovered one morning that it had been bashed overnight. While a technician was dusting off the last traces of the repair job, body shop manager John Klimowicz began explaining the business. While high strength steel is still used in car construction, thermoset plastics are becoming more common. To point out the strength of the repair work, Klimowicz relates that the same epoxies used to weld airplane panels are employed for car panel bonding repairs. If repaired properly, according to manufacturer specifications, “you can hit it with a sledge hammer and it will not break.” As to a future when driverless cars are expected to reduce collisions? “That remains to be seen.” In the meantime, Klimowicz believes there is plenty of work for Dr. Ralph’s and for the other nine or so car repair shops tightly spaced alongside this industrial stretch of Umbria Avenue.
