This sound like blush for sure which is moisture captured in the
finish before it has a chance to evaporate. I've only seen it with
lacquer but maybe this "fast dry" is acting like lacquer and skinning
over very fast, not allowing the moisture to evaoprate. With lacquer
we add a retarder to slow the skinning to allow the moisture to
escape. Typically only seen when you have high humidity.

A few possibilities a
- Moisture in material. I guess unlikely if this was the first time it
was ever opened.
- Shelf life problem and something went bad in the can.
- High moisture content in the wood.

I am not familiar with this product. Is it water based? If it is oil
based, maybe try thinning it with some mineral spirits to maybe
increase the open time to let the moisture escape. If water based, is
there a thinner you can use, maybe flowtrol or something? Also, is
this semi-gloss or satin? Those sheen killers are just white paint
pigment so maybe somehow it got out of balance and you got all of it
in one coat.

As usual, Sr. Sonoma is on his game. FWIW, I agree.

I ended up sanding the white off and trying something else. Now I'll take
more time mixing, I didn't know that the sheen killers were white pigment..

Actually, the shine killers that break the reflectivity are usually
some type of silica, flat ground to the manufacturer's specs.

These will easily collect on the bottom of the can if the material is
old, or in my experience, been exposed to a lot of different temp
changes. (For example, here we have had some days lately where the
overnight temp was 35 - 40 degrees different from the day temps).

Do yourself a favor. Go to the hardware store and buy yourself a
paint stirring gizmo with the spiral configuration on the end. Put
that on the end of your drill and stir your material, no matter what
it is, for at least three minutes in a quart sized can. More for a
gallon, even more for a five gallon.

Don't whip any air into your material when you are stirring. Air will
make bubble in your finish, even after application. A low mix speed
works fine. When the semi gloss, satin clear coat is properly mixed
it will look like clear amber in the can. Some clear flats look a bit
cloudy, but consistent. Never white.
