Purchased last fall, opened yesterday. Stirred as usual, looked ok.
Applied with foam brush on test piece of medium pored teak-like wood.
Set aside at room temperature and it immediately starts to look like
I coated the wood in white soap.
What the hey. After a couple hours no change. Almost looks like I
painted the wood with white lead.

I've used this produce before without problems, but it "might" be
some kind of reaction with the wood.
The wood was purchased at a farm sale in a batch of other hard woods
that could have been over 30 years old. Some mahogany and what I
thought was teak but I can't imagine what the heck happened.

Maybe return the can to the store and try another batch.

I am having a similar problem with the same product. The first time
I used it the room came out beautiful. The next room I did a week
later is dull. I used a foam brush both times. I went and bought
another can and went over it to get the sheen. Waited a week and did
another room and the same problem again! Just no sheen at all!
Maybe I have to buy small cans, so it's a new can each time.
Depressing! I still have 4 rooms and a landing to go. I was
wondering if I shouldn't be wiping my brush on the side of the can as
I go? I just don't understand!

Boy, that sure does sound like oxidation in the can. I assume you stirred
properly before each application. I'm guessing that the fast dry
characteristic is what's biting you. Watch for comments from Robert
(Nailshooter). He'll have definitive commentary if he does reply.
Otherwise, I'd go with your plan and assume it's an oxidation issue.
