These are some pretty good pics of rust repair on a "rust free" 240Z...

 

This stuff was minimal and most of it was not visible yet...

 

There were 2 places that had a surprising amount of damage caused by a leaky rear deck gasket/lid...

1. right hand toolbox...

2 right rear wheelwell/ rocker lip...

 

 

anyway here are some shots of the damage... somwhat cleaned up to find the extent of the damage...

 

right rear rocker lip... I got a bunch of bondo out of this area...

The repairs were going to get the lead treatment.. but I think I can better prep the repairs and get rust treatment into all the nooks and crannies better with modern chemicals..

 

I have a few quarts of metal prep and POR15 (light grey)... that should provide a good amount of rust protection...

 

everything will get seamsealer.. with attention given to not trapping water..

 

I will final fill with bondo where repairs are visible... this will require minimal bondo work as I was very carefull to keep things as flush as possible...

 

I always leave a slight depression around repairs.. but in many cases it is only a few thousandths below grade.. and the areas are relatively small...

 

The large repairs such as the rear rocker lip replacement are DEAD FLUSH.. only slight filling near the weld seams is required...

This V8 race car project is the most extensive metalwork I have ever done on one project... most of my experience has been with aluminum and polyester/epoxy... sheet steel is relatively new to me... I like it though... steel MIG welding equipment is MUCH CHEAPER than the TIG equipment I have used in other people's shops. I have not been able to justify the expense of a proper TIG rig with my wife...

I have had my hands in kit cars, kit planes, and restorations of everything from gas pumps to turbojets... I was lucky to work for a small shop owned by a retired aircraft fabrication genius.. for several years while I was in college...
