Next, the crew moved to the front of the Buick's body shell. As is common with GM “A” body cars, the bottom of the cowl boxes had rusted away due to debris, leaves and moisture rotting the panel from the inside out. We fabricated some repair panels and TIG welded them in.







This included repairing the cowl on the inside as well.



Numerous repairs were made to the Buick’s floor and body mount areas.

Of course, the bottom of the fender was also affected by the rust, so metal repairs were necessary.





The inner support had also rusted at the bottom half. This would have to be repaired as well.










Repair panels were made and welded to the bottom half of the fender skin.

Buick GS hoods are not reproduced, and our car came in with a light punch to the nose. Some time with the Spitznagel Maxi dent puller, hammers, dollies, and a metal file brought it back to shape.









The lower edge of the hood required a little repair panel, and it was finish welded with the HTP Versa Spot welder to achieve a factory appearing spot weld pattern.





Jumping ahead to the re-primed hood.

By this point, all of the bottom side sheet-metal had been repaired, so the firewall, underside of floors, and rear panel were re-sprayed with black epoxy primer. The seams were all carefully sealed with 3M seam sealers, and then the Epoxy was followed by a black Imron industrial enamel.













The owner wants to drive this car, so we coated the bottom of the car with 3M Body Defender. This product provides chip resistance, but it has a smoother texture and is easier to clean than rubber-based undercoating.

It is very typical For GM “A” body vehicles to rust around the base of the windshield, and our car was no different. Again, being a Buick, replacement dash panels are not available in the aftermarket, so we chose to remove the original dashboard and it's entirety and repair it.




The welds were carefully ground, spot welds carefully drilled, and the whole dashboard was removed from the car and placed on a stand.

At this point, Adam repaired the rusty cowl structure in the car and treated it with a weld through primer from HTP.





Then, he fabricated a new section and welded it to the original dashboard.



Once metal finished, the dashboard was reinstalled in the car and attached with original style resistance spot welds.





Once completed, there was little evidence of a repair.
