'Brushed out' a little more, it gives that beautiful color of a classic

Finish with about 6 coats of Spar Varnish . . . 400 - 600 grit 'scuffing'

I wouldn't mix the stain with the varnish in this case as it will
weaken the protective quality of the varnish at best or prevent it
from curing properly at worst.
My best idea would be to go to a good paint store and see what they
recommend. If you do want to experiment with the Minwax products,
there are UTC (Universal Tinting Colors) and other additives available.

I use stain/poly mix on pine, since pine tends to accept stain blotchy (or
is that blotchily??). With a gloss poly it turns out slippery smooth and
very glossy. However, it takes quite a few coats to get a dark color.
another option, have you considered gel stain? Adheres to the surface and
soaks in well. Since you are having problems with the wood soaking up the
color, it might work for you. I used this before I trid mixing stain and
poly.

I'm not sure where the basis for that comment came from but I'd have to
strongly disagree with it as a whole.
Varnish - thinner, mineral spirits, carrier, a curing oil (hopefully tung),
resins.
Stain - thinner, mineral spirits, carrier, a curing oil (hopefully tung),
pigments (very little).
Thin a mixture of the two enough and you've got Danish oil, thin it a little
and you've got a tinted wiping varnish, don't thin it and you've got a
colored min-wax finish.
And just exactly what do you imagine UTC's and other additives are but
colored pigments??.

What you really need is some more expertise. I *highly* recommend
"Understanding Wood Finishing" by Bob Flexner. Get it from the
library or your bookstore today. It would take screensful of
information in an email message to match one small part of this book.
Since oak is so porous (I assume you are talking about one of the red
oak species here), it needs special finishing tricks. If you don't do
it right, having the finish look the way you want is a crapshoot.

Was the Minwax rep sniffing his products? I wouldn't use a spar
varnish for an internal application. There are varnishes which are
mixed to work well inside, but don't have (or need) the UV and weather
protection you need on a boat.
As someone else replied to this thread, wood finishes contain a
solvent, pigment, and protectant. They also can contain metallic
driers and other stuff. You need to consider wood surface (red oak
has huge pores), colorants (dyes and stains), and finish each as a
separate issue. For example, why varnish for an interior application
at all? Oil-based varnishes take forever to dry, and are a pain to
keep dust free.
If it isn't a heavy wear surface and you don't need a gloss surface,
consider some other finish. A wiping oil (like Deft or Watco) with a
paste wax on top is easy to repair, and fool-proof to apply. If you
want some depth, use shellac. Again, easy to fix and easier to apply
well than varnish. Or consider one of the new water-based finishes.
They dry much faster than oil-based finishes, which reduces their
exposure time to dust, and generally finish clearer than oil.

See Flexner's book.

I wouldn't. Most of them don't know much about wood finishing. Look
for a store that specializes in hardwoods and cabinet- and
furniture-making supplies for advice. If you have time to look
around, a lot of cities have woodworking clubs. These are a source of
woodworking expertise, but, like boatbuilders, woodworkers are an
opinionated bunch and you can find different answers from different
people, who both might all be right.
Good luck.

2 coats gave a nice gloss. Color will vary by the mixture. Again, trial
and error. One thing I did notice is it spread much smoother, due to the
thinning, and dried faster.

If you need UV protection, a Marine varnish (SPAR is a 'long oil' or soft
finish}or a 'clearcoat' {like Minwax Polycrylic}. The Poly will give a
water-clear, hard, scratch resistant finish . . . non-UV protective . . .
for indoor use.
'Brushing out' simply means to put on a thin coat, or brush the paint/stain
out to a thin, even layer. If you 'flow on 'Bombay Mahogany' like varnish,
you will get a VERY DARK and heavy coat. If you brush on a thin coat, or
thin the product with a little solvent, you'll have a lighter coat & color .
. . just make sure it's even. If you apply when it's cool, or just a little
warm, it will 'self-level' before it dries and the brush marks will
disappear. Typically I use a foam brush which all but eliminates this
problem.
'Wolfie', if you are reading this . . . I don't know about the 'samples' but
I GET that type of final finish. Be glad to send you a photo of a rudder
blade I did.

To get the color I want generally takes 3-4 coats.

I think it really depends on what kind of wood you're using. I do get
those kinds of results on maple, birch, or even poplar, but oak will
simply not take the stain that deeply, nor will it ever look as 'flat'
as the store demo because of the grain. I figure a sanding sealer
would fix that, but the items I use oak for, the look of the deep
grain is actually desired.
I really need to shorten my posting ident to just Xane ;)
