The Zinsser Bulls-Eye is a water based product and will
dry faster than you can get it on. It also sands pretty
well.

So, I'm out here sanding this Pinewood Derby Garage project, by hand,
because it's a nice quiet Sunday and I don't feel like listening to a
sander and don't want dust flying all around me and the shop.

What I need to know is: is there some kind of super fast drying
paint, maybe to be had from a craft store, that will be easy to wipe
up when it spills and be easy to sand when it's dry.

The meeting lasts for an hour and I figure the painting will take
forty five minutes. It would be lovely if the paint would dry enough
to pack during the remaining fifteen minutes because watching paint
dry is a little to much Zen for a Monday night.
