Our recently aquired home has a nice VGF craftsman style door with 2 panels and ledge under the window. I don't think it has ever been refinished from original and has some spaling? of the grain, is graying and has no film left. the door faces south and is getting full sun for part of the day.

I am considering
1. remove door
2. sanding with 100 / 220 both sides
3. inside gets satin helmsman varnish, have used this for years, have some in stock and its always held up well.
4. sikkins ( which product?) outside. transparent color for more uv protection.

what do you think?

should i use a different product? My Father really liked using sikkins on the teak on his boat and i remember it holding up well and looking good.
