From Amazon:
- CLASSIC MARINE VARNISH contains premium tung oil, phenolic resins and UV blockers for a beautiful transparent amber finish on all types of interior and exterior wood on boats, strip canoes, kayaks, outdoor wooden bar tops, garage doors, furniture and more
- DURABLE URETHANE SPAR VARNISH with maximum UV resistance; it remains flexible after curing, and won't peel or crack when the wood expands and contracts with seasonal humidity and temperature changes
Josh, this type of Varnish is a very high-build product which in my opinion turns wood into plastic like the old resin tables from the 70s. While I like that super polished European cabinet finish in a Yacht with no grain and high gloss, not on my BBQ or home cabinets.
I don't like the Amber finish from oil-based finishes affecting my stain color and continuing to yellow more each year. GF is milky white in the can but crystal clear when sprayed or brushed. I used a cheap HVLP spray gun on the compressor for GF to get the light film thickness.
GF you apply 2-3 very light coats, and as I mentioned you can flip part in 5 minutes to paint the back if you use nail sticks so only a few points touch the back.
I would guess Varnish you would have 3 days into finishing, vs less than 1 day with GF. Rockler sells online or in-store, I would say you might want to try on one of your wood working projects or grills
Here is the handle with 3 coats and really bright reflective kitchen lights, but you can see White Oak grain still exists. White Oak is tighter grain and holds up better outside than Red.
