Wouldn't the seats have already been in the car when the undercoating was applied , that was an operation I thought that was done when the car was pretty much fully assembled ? If this is the case that strip of tape on the floor wouldn't be like that ... but plants vary I guess as to when what was done ?

I remember a reference resto that was reundercoated , when the car was originally documented the seat bolts protruding thru the floor were wrapped with masking tape ?

John,

Its hard to say. The way that this car seems to have been done was that the undercoating was done prior to ceratain things being installed such as suspension and drive line. The axle bumps appear to have been installed prior to the undercoating as there is undercoating on them. The drive shaft hump also has undercoating completely on it also. The hangers and shackle areas appear to also have either been taped off or had some kind of template on it to prevent the undercoating from getting onto those mounting areas. I will try to post more pics of these areas if I don't have to resize them.

JohnRR,

From what I have seen, the St. Louis cars had the undercoating applied prior to the interior being installed. This is why they would have taped off the holes to prevent any spray from getting inside the car. Probably similar to why they masked off the mounting areas for the suspension and other stuff so they could get proper torque and not have to worry about nuts or bolts loosening up causing a warranty issue down the road.

another undercoating pic. Im guessing this is where it was on a cradle or some point of holding the body since there is a similar area on the opposite side.

Sometimes the undercoating was included in a group like A04 or A05 depending on the year, make, plant, etc.

As a stand alone J55 option on a tag...I don't know if I've seen it either. I'll have to keep checking.




My 69 500 convertible is an A05 car, hood pad, front and rear bumper guards and undercoating




I
Is A05 on the tag ?




John, my tag is long gone, but this car/tag is one vin after my 500 and other than colors is optioned almost exactly like my car. AO5 is on this tag so I can with reasonable certainty assume it should be on my tag too.

I don't think that's factory undercoating, it looks nothing like how my car looked and its from the same plant and time period

Hard to say. Maybe it was applied by someone who was covering for someone on break? The undercoating is the same appearance and consistency as the rest of it. It is weird though as it has a similar pattern of coverage on the opposite side as well.

One thing I have learned is that each car is unique as to how it was assembled and to never say never when it comes to Mopar!

Is there any undercoating behind the gas tank or overspray on the tank?

There is either undercoating on the front part of the tank up by the sending unit or it is just very dirty and greasy. I seem to recall that there was undercoating on the top sides of the tank but I don't have the car in front of me to double check. Here are the pics I took the last time I was at dads house.

I gotta agree. I don't think that is undercoating just dirt and crud that gets on there over the years. It isn't thick enough and in the right places to be factory undercoating.

I wonder where the body would have been supported during the application of the under coating at the factory?

I also highly doubt that dirt and grime will leave an almost perfect shape like that. I still think it is factory under coating and a cardboard template was used or something was blocking out that area for a reason. If it was grime or dirt, I would imagine that it would come off fairly easily with digging my finger nail into it unlike the undercoating would. But again, I am no expert on this. I am just going by observation and taking into account the other areas that were taped off or covered up while the undercoating was applied, similar to the areas where the leaf springs mounted up to.

I think it's dealer or aftermarket undercoating, not factory, with no A05 on tag or build sheet to back up claim and the way it looks compared to my car it's just not factory IMO .

I dont know if this will help, this is before I removed the undercoating, I think this is after I pressure washed it
