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 had the exact same thing happen to me when finishing three computer
desks. My first coat went fine but it "fogged" white during the second
coat. Even though it was temperate and dry inside, the temperature and
humidity outside was high and apparently some of the moisture seeped
into the poly. I ended up dipping the desktops to remove the poly and
recoating a week later and they came out fine.
