I've read opinion here that says you can get excellent results if you
understand your materials. Elevated temperatures to allow very rapid drying
was a major factor AFAIR.

My experience, long ago, was that it is doable with great care, attention to
detail and consistent technique obtained by experiment. ie can be done but
needs dedication and discipline.
