It was a pretty frustrating day on the car. Did some unsatisfying stuff like sanding the underside of the bonnet and the drip edges inside the front wings.
And I sanded down the inside of the trunk and sprayed some rust conversion product on it. It's called Krud Kutter I think. Like most of those products it's a phosphoric acid based solution that turns the rust into some other inert compound before painting it.
The worst part of the day however was when I decided to remove the lock from the trunk so I could sand the rust around the outside. After removing the part inside that connects the button to the latch assembly, I shut the trunk. Crap. Even though I knew how the latch worked and could picture it, I tried for an hour with various tools to pop the latch from the inside by reaching in through the tail light holes. No luck. In the end, I drilled a 1/8" hole below the button and popped the latch with the tail of a file. It's bad enough that it's taking so long without creating more work for myself. Now there's an additional hole to fill.
