(5) Why should weatherstripping be replaced on 1957–1958 Pontiac hardtop vehicles?
Over time, the original weatherstripping on 1957–1958 Pontiac hardtop models can deteriorate due to exposure to sun, moisture, and temperature changes. When seals crack or lose flexibility, they can allow water leaks, air drafts, and road noise into the vehicle. Replacing worn weather seals helps restore proper sealing around the doors, windows, and trunk, maintaining comfort and protecting the interior of classic Pontiac vehicles.
