Resto question - A post gap

[EffinDuff]

For all of you body experts out there.  I just about finished the stripdown of my 72 charger for resto and came accross these spots.  As you see they are on the top of the A post on both the passenger and driver side.  They appear to be relatively uniform on both sides, I am thinking they are possibly a factory lead fill spot? 

The body shop or whoever painted it orange (second paint job, now it is yellow) filled and modeled those spots with bondo.  Other then that the roof looks like its in good condition.

Any light on this would be appreciated.

need to replace the metal if you can by finding a donor or making your own patch.  Maybe someone on the site has some donor material for you.
At the stage the rust is at, you, IMO ,will not be able to blast and fill again without it coming back relatively quickly.
Guess it all depends on how far you are going with the resto.

Strange how it built up on both sides evenly.  It's also strange that the rest of the roof appears to be very solid.  Is this a common spot?

EffinDuff,
I see no need to make a patch. That is a leaded seam area from the factory.
My advice? Pull the glass out, & have the area thoroughly sandblasted clean. Then, spray on a good metal conditioner such as from DuPont. Apply a few coats of epoxy primer & you're done treating the metal. Should last a long time.
Looks like the previous repairer just used body filler, as plain body filler is porous & will allow moisture thru. Once sandblasted & cleaned, either use a good fiberglass based filler or a metal-to-metal filler for this seam.
