is this shellac and what can I put over it?
I started tackling the orangey mahogany trim in my 50s house. The finish is bad or gone (can't tell with the dirt and possible fixes over the years). It cleans up pretty well with mineral spirits, with lots of grey-green gunk coming off. It has spots where it turned white with water over the years (towel bar too close to the door jamb).
Is this likely shellac? I don't think I'll be able to strip it off entirely, whatever it is, so I'm wondering if there is anything I can put over it to protect it a bit. Can I just rub in a little polyurethane? Will it stick?
If I do get it stripped satisfactorily, what's the best finish for natural mahogany to maintain its yellowy goodness and chatoyance? I'm scared to try shellac. :/
Suggestions please? Thanks!
