(3) Why should worn weather seals be replaced on a 1969 or 1970 Pontiac hardtop?
Over time, original rubber seals on classic Pontiac vehicles can crack, shrink, or lose flexibility. When this happens on 1969–1970 Pontiac Bonneville or Catalina 2-door hardtops, it can allow water intrusion, wind noise, and dust to enter the cabin. Installing new weatherstripping restores proper sealing around the doors, windows, and trunk, helping keep the interior dry and reducing exterior noise.
