No more work needed.

Minwax works fine for me but lots of people hate it. Just use any oil
based stain . And you only need one coat. Water based stains actually
put the color down a little stronger but they raise the grain and
that's a whole issue you don't want to deal with.

I have the most success with Polyurethane. Again I use Minwax high
resin. I mix it 50/50 with mineral spirits and wipe it on. You won't
see this on that can but it's fiune to do it this way and have zero
drips. My technique is flood the surface well with a brush, then wipe
it down with a lint free cloth. I prefer to let the cloth get fairly
saturated. You want to leave a barely wet surface. Let dray at least 4
or up to 24 hours between coats. Sand very lightly with 400 after the
second coat. Be real careful on the edges. wipe on one more coat.

Final step is to use good quality wax with 0000 steel wool. Put it on
very thin in circular motion. Let dry well. Buff to a beautiflul
finish.

Also, whatever you do, I'd test the entire process on one small section
or similar wood first.

The combo tint and poly (ie Minwax Polyshades) is similar to a
technique pros use with tinted film finishes. However, unless you are
spraying, it is real hard to get a good, even finish this way. It can
be done, I have done it but the success rate is much lower in my
experience.
