Smells like tung, behaves like tung, must be polyurethane.

Well ignorance is bliss... Arm-R-Seal pretty much *is* poly for all
intents
and purposes, while Seal-A-Cell only contains slightly more oil. No ifs,
ands, or buts about it. Do you think there's really tung oil in Minwax
Tung
Oil? It says tung oil right on the can, and in fact, it's called "Tung
Oil"
The answer is, again, probably not or at best very very little. It's more
likely to be a mixture of various oils and ALOT of paint thinner. Many
different elixers are called "Tung Oil" for mass marketting today. But
even
real tung oil doesn't offer anything in the way of protection that linseed
oil doesn't, anyhow. Now, these finishes all have different smell
characteristics because they're wiping varnishes with varying amounts of
oils vs. resins and solvents. So like I said, I believe Seal-A-Cell to
have
more oil than Arm-R-Seal, and so the protective characteristics of
Seal-A-Cell aginst products like household cleaners is going to be less
than
Arm-R-Seal. And furthermore, if comparing Arm-R-Seal to straight poly
such
as Minwax, one will find that the Minwax will win against harsh household
chemicals. It has to do with the resin contents of each of these finishes
that varies... More oil vs. more resin. And the higher resin content of
Minwax poly vs. Arm-R-Seal or Arm-R-Seal vs. Seal-A-Cell gives the
greatest
protection. This is why Arm-R-Seal is the "top coat" product, which begs
the question: why bother with the Seal-A-Cell undercoat at all? It's a
good
question becayse the line about oils sealing and penetrating is sooo
overblown. Nothing seals like shellac.

FWIW

I really doubt it. I have used poly for several years. Smells and
behaves
nothing like polyurethane.

Says right on the can Tung oil/urethane mix.

Well I hate to break it to you, but Seal-A-Cell and Arm-R-Seal are
basically
just poly. They're certainly a very short oil finish, and probably
don't
contain any tung oil at all. "Tung oil" is kind of a catch phrase for
alot
of things these days.

Having lost mt patience with polyurethane I decided to try something
new.
I
made a mission bed for my son and I decided to go with a Tung
oil/urethane
mixture (General Finishes, Sealacell). How many coats should I apply?
The
directions on the can are a little sketchy.

Thanks
