1) Put a layer of Citristrip Stripping Gel (Home Depot) on the targeted area. Let this sit for about 1/2 hour. This is enough to take the bulk of the old finish off without really getting to deep into the base color. What it does best is get any Poly that has gotten yellowed from water getting under it and really pulls that stuff off.
2) Scrap the stripper off and then clean with mineral spirts or similar, let dry completly.
3) Sand lightly with 200-400 grit just to smooth any gain that might have raised up a bit. It should need much, wipe away and dust.
4) Next take a rag and wipe on Cherry colored "Watco Danish Oil". This will fill in any irregular colored spots and smooths the color out. let this sit for 1/2 hour or so and then wipe it off.
5) Let it dry for at least 72 hours. then start adding new Poly in whatever flavor you like. I use Minwax Fast Drying "clear satin"
I got the idea for the Watco oil from MaineSail on another forum, so a shout out to him.
Hope that helps.
