I didn't know that General finishes was marketing their "all in one"
finishes as gel finish. Checking your link, it indeed falls under the
"oil based wood stain SEALER" category, not stain.
General used to make a gel stain, that was indeed just a stain. I
have used it, and it wasn't that good. It didn't have the body to
make it a good gel product as it was too watery and the percentage of
solids was too low.
I see now they are marketing the on Minwax style colored poly. To me
this isn't stain, although it stains what you put it on. Of course
they can call it caviar if they want since it is their product, but
stain or dye is a colorant, not a finish. The stuff they show is
indeed probably some kind of lightweight poly, with enough colorant to
leave something behind including a small amount of protection, but not
enough that they feel the need to recommend a top coat. I wouldn't
trust the pros that you are consulting on this if they actually think
this is a true gel stain.
> But that fact that Varathane also offers a Gel Stain kind of indicates there must be some association, I mean what else does Varathane brand make besides poly?
Varnish, spar varnish, sealers, wood prep products (commercial only),
specialty coating (commercial only), paint, commercial grade finishes
for wood floors, and Rustoleum products.
They also make real, true stains, not just gel finishes:

> Anyway, I know it makes some people sick to think they have put poly on their projects but I use it where it is the right thing and I have left gel stain coated items with no other top coat finish to long lasting good results.
If they are "gel stains" as referenced above, that should work.
Personally, having been to enough training and education seminars to
fill a school year, I don't have any problems with poly. What folks
don't understand is there is no magic involved, no special formulas,
no unusual formulas. Just about any finish can be considered
polyurethane. Polyurethane only means multiple types of urethane
resins are in the mix. The types of solvents and carriers differ, but
they are almost all polyesters. And according to Sherwin Williams lab
guys the difference between poly and varnish in today's formulations
is almost nothing for the better brands.
> I mean there is surely some pretty strong chain binder on there because they all tout their ability to be used on fiberglass and that takes some adhesion I suppose.
I don't know what a chain binder is in this case... but I can tell you
that the thing that makes the gel stains work is the heavy concentrate
of solids and the medium VOC of the carriers. Check out the MSDS
sheet pdf for Old Masters below. The huge amount of solids is the
reason they are so expensive. There are also other factors. When
Bartley's used to make a true gel stain (no or very little added
resins) this was on their literature:
"Our gel products start
art life much the same as their liquid counter-
parts. A powdery thickening agent is added to the
liquid mix of resins, pigments and mineral spirits.
In a process known as thixotropy, 100-gal. batches
are put in a machine resembling a large milk-
shake maker. As the ingredients are stirred for at
least an hour, the chemicals react together and
heat up to around 150°F. Once this temperature
has been reached, the mixture must be canned
quickly before it cools and becomes the thick mix-
ture known as a gel stain.
> So not proof positive other than the General brand I guess.
Proof positive for >>their<< all in one product labeled as a gel
stain.
As far as Leon's example goes, at least Bartley's is honest. They
don't claim it be a stain. A quick look at the can and it is labeled
correctly as a "gel finish". So it is like using colored Waterlox or
their brothers and sisters, just a different consistency.
I have used Old Masters stain so much and so long I don't look at
other brands. It is a true stain, with no finish in it. It is made
as described above by the old Bartley's recipe before they Minwaxed
into an all in one.
You can see their product here:

And by reading the MSDS sheet you can see there are NO urethanes added
to the mix. It is a thixotropic stain formulation (again, SW guy said
that just means thickened with solids and heat), with no finishing
properties. Top coat of your choice is a must.

Personally, have dyed some poly and used it using Behlen's SolaLux.
That's it. I can't see a time when I would use and all in one product
as I have never seen any finisher (certainly myself included) that can
maintain complete control over the color and finish over anything more
than a small project. That's just my preference. The paint guy at
Home Depot tells me the same thing my Woodcraft buddy does, and that
is they sell the daylights out of that all in one stuff.
