So, I have rescued a lovely old desk that was destined for firewood from my workplace. It is lovely and heavy and has the most beautiful grain - the only thing is it needs a bit of love, as you can see on the top surface. The varnish is chipping off and it has some watermarks. From what I can tell by by internet sleuth work, I need to strip it, sand it, and re-varnish it with a very similar if not the same colour varnish. Anyone an expert?
