I previously added backing reinforcements and filled some cracks in the body work:
I used too much SteelStik and left a blobby mess, thinking I could just file it down smooth. After an hour with a file, I gave up on it and just sprayed the spots with Krylon Fusion Matte Vintage Blue (of course).
I recently picked up handy Bandfile Belt Sander from Harbor Freight (link):

Not so much of a big deal on the side of the fender, but my regular palm sander wouldn’t have fit up in between the rear bumper and rear skirt where the other big ouchy is located. I used a little too aggressive of a belt , but it took the blob right off.

The story was the same around the back.

I cleaned off the affected areas with brake parts cleaner, then Sprayway glass cleaner.

Then I added a couple coats of primer.


And again on the rear…

Then I wiped it all down again and sprayed it blue.


It’s rough as guts, but at least it’s smoothable-outable now. Those fenders are covered in a thick layer of filler, though the steel as visible from the underside is totally smooth and unharmed. I’m guessing they may just have rust pitting like the roof did and bonnet does.
While I’m out here, I may as well fit those new wipers I bought.

This after giving up on finding springs small enough, yet strong enough at any local hardware or auto parts stores, as seen in the series of posts below:
