Blushing
1. Caused by the relative humidity being too high, or the solvents evaporating
excessively fast, allowing the temperature of the surface to drop below
the dew point of the air, causing moisture to condense on the surface.
When spraying a dope finish use one part retarder to three parts thinner
to thin the dope to spray consistency. A mixture of one part retarder to
two parts thinner can also be sprayed on the surface in a very light mist
coat to help eliminate the blush. Don't soak the surface.
