The rust battle rages on

Another common spot to check for rust on an s30 is underneath the battery tray.  Apparently the battery tray hose can break and leak acid on the body underneath.  Additionally, the shape of the area underneath the battery makes it prone to harbor dirt and debris which in turn will hold moisture and cause rust.  The latter is the case with my 280z...

Aside from the rust under the tray, the engine bay is a mixture of the original factory green and a flat black which was seemingly sprayed over the factory color with little to no prep.  The black has been flaking off in chunks.  

Inspired by the newly painted radiator brace, I decided to address both the rusty tray area and the multi-color  engine bay (or at least one side of it).  Donning a cordless drill and a set of wire wheels and brushes, I roughed the surfaces in preparation for primer and paint.  I then carefully masked the engine and other bits not being removed.  I didn't get any shots until the primer and color coat were applied, but I can say that it looks a lot different with a single color adorning the side of the engine bay.

Only time will tell if the surface rust underneath the battery makes another appearance.
