Will paint dry in space?

Paint is liquid and solid, and the liquids would usually evaporate to leave the solid colour on the wall. Does that mean that vacuums would affect the way that paint dries?

Or does the energy from the sun still cause the paint to dry?

Yes, paint "drying" is the release of the volatile solvent from the paint.  An analogous term is "off-gassing".  On earth, if you want to "off-gas" a solvent, you put the part or article containing the solvent into a vacuum chamber.  The lower pressure causes any volatile material to (whether it is a petrochemical or water) boil off at a much lower temperature, leaving only the solids.  Its the same with paint.  So, in fact, the process should be much faster in space, but I'd expect the process to be nearly explosive, resulting in spotty coverage, as the boiling would be extremely violent...  ;)
