I then gave it two coats of spar varnish. Now the varnish is weathering/deteriorating. It is not coming off, just looks weathered and dark in some areas.
The door is heavily carved and paneled. I can't see how I could possibly remove the old finishes. The wood is solid mahogany.
Can I use a "Solid Stain" on top of the old varnish? That way the exterior finish would look uniform, without looking painted. ??
