OK, for us youngins in this realm, can someone explain what it was the article did wrong, cuz I'd be thinking that's the way to do it. I'd since I'm getting mine painted in the next couple months, I might be inclined to direct the painter in that direction if I didn't know not to. If it's already been discussed, a pointer to the thread would be appreciated, not sure what to do a search for that would cover this.
Rather than try and explain what "they did wrong" in this thread I direct you to the area of the site that relates to the year and plant your car was built for illustrations, pictures and information specific to your car. If you can't find a thread that deals with the question after a search and some reading please feel free to start another and help will show up
In general -
1- the sound deadener was applied at all plants during the classic years prior to exterior color application (so the final thing you see on the surface over 95% plus of the rear wheel well sound deadener was body color) Yes the text does refer to seeing some body color in the area on a different car (65 Mustang) but the picture will lead many (since so many will just look at the pictures) to look at the picture details and move on
2- It was applied to the bare unibody so no gas tank, fuel lines, rearend, brakes, wiring .... with sound deadener overspray.
"02. Mask off the fender, rear axle, brakes, and leaf springs, but leave the gas tank and fuel line exposed, as the assembly plant did."
"08. Notice how the coating splattered onto the gas tank, imitating the factory look. The assembly plant did not bother to mask off the tank or the fuel lines, which also will have an overspray pattern."
3- The example they used to show "Restorers consider this work artistic." body color over rear springs
