1971 Datsun 240Z - Restoration


Recommended Posts


Upon inspection of the rear valance, we noticed that the panel was being pushed up between the spot welds - which usually indicates that there is rust beneath the surface. After carefully removing the rusted panel, it was media blasted, repaired and re-installed.

How did you treat the bare metal between the panels? Are you TIGing or MIGing?

Every panel prior to reassembly is first media blasted clean, if the panel is going to be welded those areas that will be affected by heat are coated in a weldable primer.  If the area is not going to be welded and/or will not be affected by the heat of the welder, such as the inside section of the new frame rails below the flange. (we will post pictures of those later after they are finished with them) Then those areas are coated with epoxy.

 

As for our welding methods about 90% of the work we do in the shop is TIG welded.  If I can get the back side of the panel to hammer and dollie my weld seam I will always without question reach for the TIG.

While inspecting the vehicle, we noticed a large rust hole under the cowl. We scraped away the seam sealer and revealed a significant amount of damage compared to the rest of the vehicle. We removed the HVAC duct and repaired it and the surrounding area.

Thanks for the info. I thought it looked like TIG. I have a MIG rig and have never tried TIG. Working in the front cowl area is no fun but the worked turned out well. Did you consider using the Tabco patch panels for the wheel arch and dogleg instead of fabricating from scratch? They are pretty close...
