Any one step finish is a compromise---craftsmen and craftswomen have been finishing wood products for hundreds of years and have yet to discover a decent one step process.

Stains color wood while finishes protect. A one strp product cannot do a good job of either.

They will be much further ahead by simply applying a finish---and I recommend varnish instead of poly. Varnish is faster, easier, and can be repaired(spots/runs/etc.) when poly products cannot.

The only thing expert finishers hate to hear more than, "Slap on some poly," is "Slap on some Polyshades."

First mistake was probably starting with sanding.

Ugly cabinets can not only be costly to repair or replace, but can be a big turn off to a potential buyer.

A challenge here...
For selling reasons, why do it at all??!?!?!

You're potentially making more work for a buyer if they don't like it!
Since you've already sanded, a good brushing-Lacquer is the fastest way. Each coat lightly dissolves into the previous coat. Not as durable as Poly, but faster between coats.

Because the Realator recommended they spruce up the finish!..And they asked someone else what they did....
Anyhow it's done. Not the way I would have done it, but they they didn't wait for my recommendations!

In this market, fast sale is not likely.
