10/15/25: Today I wrapped up the interior painting!

I made the call to push back installing the air distribution system for my new compressor in favor of getting the cab painted. Time is really ticking for painting, so I prioritized getting the cab done before it gets too cold.

In addition to painting the rest of the interior of the cab, I decided to apply another color coat to the dash. This was for two main reasons: first, to achieve a much better finish than the initial spray can application, and second, to absolutely guarantee the color match. I spent a significant amount of time wet sanding the dash to eliminate any residual orange peel from the spray can, while a maroon Scotch-Brite pad did the trick for prep on the rest of the cab.

The actual paint application went quickly and without incident. I used a PPG single-stage polyurethane enamel, mixed at four parts paint, one part hardener, and one part activator. I laid down three coats on the cab and then applied two additional coats to the dash, building on the earlier work.
And the results? The dash looks truly excellent – very smooth and shiny, just what I was hoping for. The rest of the cab also came out great. I wasn't as concerned about achieving a glass-smooth finish there, as it's riddled with spot welds anyway.

I had a little paint left over so not to let it go to waste, I painted the underside of the cowl vent and the interior windshield trim, applying coats until ran out of paint. The trim will still need an additional coat.

So, with the interior officially squared away, it's full steam ahead to the exterior!
