1946 Chris Craft Brightside U22 Varnish Buffing Update

John has worked last week and through late yesterday to wet sand our 1946 Brightside Chris-Craft U22’s topsides and transom from raw, fully-cured varnished surface to one that is as flat as glass.

Once he’s finished wet sanding the decks, covering boards, seating elements and dash, it will be time to buff everything using three Presta buffing products, at which point she will be blindingly glossy.

We buff with:

  • Presta Ultra Cutting Crème
  • Presta Ultra Cutt Light (PST-133-401)
  • Presta Ultra Polish (Chroma 1500)

John’s sequence:

• Wet sand using 3M wet/dry paper on a hard rubber sanding block and making successive passes with 600, 800, 1000 and 1200 grits

• Wet sand using Mirka sponge-backed discs and making successive passes with 1500, 2000, 3000 and 5000 grit using one of our pneumatic palm random orbit sanders. (He adds a half-inch-thick soft backing pad for 3000 and 5000.)

John insists on changing the water at least three times during each pass, which keeps the surface clean and minimizes scratching. We will be back once he’s reached buffing time.
