1/32 Hawker Hunter - Spray can question

Generally, I find it easiest to build as much as possible before painting.  Assembling painted parts requires a lot more care than assembling un-painted parts.  The main reason I have for leaving parts off and assembling after painting is when they are different colors.  I built a Huey recently that was supposed to have its horizontal stabilizers painted red while the rest of the chopper was olive drab, so in that case I painted separately and assembed after painting.
