Rear Quarter Panel Repair Ideas Options

[TargaToy]

So once again I find myself going where the sun don't shine.

Eventually, I plan to post the receipt from where the body shop charged the interim owner for "replacing quarter panel"...but that's fun for another day.

Here's my question: Am I correct that, from the factory, the little void in the point at the rear of the quarter panel (above the tail light) is left empty--or full of spray foam--and that there's a very large glob of seam sealer supposedly preventing tire-slung moisture from finding the foam?

I had to open mine up all the way and I'm toying with actually welding in a custom baffle in front of that pointed tip so that I could seal it up tight from the front side of the baffle. I would do this as part of the process when I fit in the new fender section.

What I want to do is make sure moisture can't get into that rear point and fester.

Anybody who's reworked the rearmost part of the fender/light socket, what have you done???

I like ospho and use it on almost everything BUT. If you leave a puddle and let it dry or a run when you paint over it, it will make a place that is hollow, it bubbles up, and will easily come loose later on. These places are sometimes hard to see till after the coating on top dries. On a 42 ford jeep I had put so much on while I was doing the whole tub, we decided to reblast it to get it nice and clean for the epoxy coat. I know on the inside of longs and places you can't get to this is tough though. I would suggest useing a air hose with a long blower to try and remove the puddles in the cavity, this might also get it in the gaps in the layers of metal between the spot welds. All you can do is try to do the best method you have available.

I haven't tried it but I bet there web sites on repairing unibody cars and re rustproofing the cavities. I know for a fact only high end shops bother with this.
