Boat finishing

Mark Ramsey takes us through finishing a boat using the roll and tip method of application. Discussion of finishing materials is included.
Member Charlie Ehm makes this input to boat finishing (specifically the Salt Bay Skiff):
You have several choices. One is to not paint the boat, but to use Teak oil instead or Tung oil. For the interior, that's the easiest, fastest, and -in my humble opinion- the best way to go. At our shop at Green Anchors, there an example of the Tung oil approach. I oil the interior of all my boats (and varnish their exterior).
Teak oil is a one-coat application with a follow-up coat in 2-3 months and then once a season. Tung oil requires three coats and no follow up. You can Teak oil a Salt Bay in about 40 minutes. Tung oil requires a bit more time to apply, because you're scrubbing in the oil rather than than brushing it on. The huge advantage of oiling an interior -rather than painting it- is the prep work requires little to no sanding.
For the exterior, with its broad, easily sanded surfaces, painting is a good choice, though I've oiled exteriors as well. If cost is a concern, then use Metro's Latex at $15/gallon. It's a very superior product I've used extensively, both indoors and out. Color selection is limited. A choice that would give you more color selection is an oil-base porch paint.
If you choose to paint, then prep work is crucial. That means an initial sanding and sanding after each coat of primer and each coat of paint.
