The last major task in getting the Chevelle back together is to clean up the underside of the hood which, like everything else, was undercoated (heavily) when new. I’d be skeptical, but where the undercoating failed, there is some surface rust so maybe they were on to something.
The process is the same as it was to remove the undercoating from everything else which is to take a 1" putty knife and scrape away the remaining undercoating. Fortunately, most (but not all) of this is very dried out and near failure, so it comes of relatively easy compared to stuff which is still moist and goopy.
I’m currently about halfway through, and it’s been a pain in the ass (and shoulders). It’ll take another couple day’s worth of evenings to finish scraping the hood clean. Once that is done, it will go out to the garage (displacing the 4runner for a couple days) to be degreased, have the surface rust sanded out and generally be prepped for paint, and get painted black before getting bolted back onto the car.
Speaking of the car,
Other than fluids and a couple very small items (air in the tires, a piece of weatherstripping at the rear of the hood) it is ready to go. The engine will be fired up for the first time... uh... soon. Probably next weekend. Not in a huge hurry since it’s not like I can take it anywhere without the hood (too many cops) and it’s still winter anyways, so the only place it’ll be going anytime soon is into storage because reasons.
