..In Jeff Speegle's document on "Restoration Support 65 San Jose Unibody (Undercarriage)", paragraph 13 mentions that "On some cars (approx 40% of the sampling) the bottom side of the front fender received a single pass of the sound deadener applicator."
Is this referring to the removable fender and not the outside of the engine compartment?
Since it states fender I was referring the removable fender. Not the inner fender panels, shock tower visible from the wheel side or the section of the firewall
Is there a time frame of which cars got this application?
Like the inner fender panel pattern one might see these all as random patterns but the majority appear to fall into patterns. Workers developed methods and patterns that would satisfy the inspectors and would figure that out quickly to get the job done in the allotted time allowed for the task.
Some times one would do extra, pause longer in a spot than on the last car, bend a wrist and direct the product in a slightly different direction. If too far off then do an extra pass to get the job done. Does not appear related to where the car was being sent - type of interior or other possible things from what I've seen. Of course the 40% of surface coverage is an estimation and an average since some might get 30% or 60%. Just trying to explain to the reader.
Here is an example of an example were the worker passed the wand/applicator over the rear firewall and splash shield surfaces, the bottom side of the fender (catching the inner fender lip to help with sealing that seam) and down over the head light bucket area and front splash shield
