His car had O rust and is a dry CA car he's had since 1977. The factory stuff sprayed on the inside of his doors was still fine. If it were me, I'd probably roll some Frost King or whatever in the doors and quarter panels when the glass was out. The stuff is not very heavy, and seems to really "tighten up" the car. Beware of some stuff, though. I went to an autobody class a couple of years ago, and the instructor told us of an old car (I think it was a Packard) that was destroyed by the guy shooting that yellow expanding foam into the rockers and a-pillars, etc. The stuff turned out to be acidic and a water-absorber, and his car rusted out everywhere within a couple of years and was not repairable.....but it sure was quiet for a short time!!

Expandible foam!!!!! What next? Blown in attic insulation???? A former owner of my house is / was an expandible foam junkie. It was like he told his kid "Go put this everywhere you can feel a draft"!!!! For better or worse I replaced a bunch of doors and windows with quality Andersen products and ridded myself of the Foam! It is a HUGE PIA to remove even if you can access it. In my case it went out with the old windows!!!

I am thinking that the doors and the roof as well as the area behind the quarter windows is gonna get done on this car and my car. Also, some A-Body cars had a cardboard / fiberboard divider between the trunk and the rear seat. I have to think that the back seat (without that board) has to be a huge source of warm air from a hot trunk. Said another way any cool air from the A/C that "leaks" thru the rear seat is wasted trying to cool the trunk. I am for certain getting one of those boards for my car. I plan to over it with insulation and install it behind the rear seat. I have learned a lot about this insulation game from the improvements achieved in houses..it has to be the same for the cars...keep the heat out and keep the cool in for summer comfort. Learning about the various products out there is very interesting. Thanks for your help and followup!!!!
