The bus and many small parts got a coat of high build primer tonight and last night. I was even able to get started with block sanding. The bus has very long flat panels so I’m primarily using a flat sanding block that’s about 18″ long, this is doing a great job of knocking down high spots that I’m not currently able to see or feel, but that would easily show up on the shiny top coat. The sanded surface can be ‘read’ while sanding: low spots stay shiny since they’re not touched by the sandpaper, and high spots are the first to have their texture disappear since they make first contact with the paper. Several more iterations of priming/sanding will be needed to get it as smooth as glass.
