Interior substitute for spar varnish7/3
I'm adding some cabinetry and millwork to match previously completed work. Finish faces are all Fir marine plywood. (Industrial/loft look.)
Prior work was finished with a spar varnish, applied by brush. Of coarse, the tung oil in the spar varnish oxidizes/darkens over time. We don't need to match the tone immediately, but want it to age similarly.
We are considering rubbing in a coat of tung oil or danish oil, followed by shellac as bond coat and then a typical Centurion topcoat.
Spray the spar varnish.
The spar is dark because of phenolic resin, I'm not sure there's much true tung oil in Spar.
I personally agree with the previous guy, you're going to need to use the Spar again. it's such a unique cat that I don't think anything will make it age similarly.
Thin it with high-flash naptha. I can get a really good "100-flash naptha" at my local Sherwin Williams. This will help it flash off after spraying just a little quicker, and allow you to spray slightly thinner coats to aid in quicker curing in a production environment. I'd rather do 3 thin coats that cure quicker (less dust) than 2 thick coats that take longer to cure.
