See if dust gets on it easily, if it does, you'll want to cover it with a cardboard box or something.

Remember, if you mess up, let it dry first. You'll cause a bigger mess if you try to fix it before the paint has dried.

Make sure you do it in a wide open area or, if you're going to construct a make shift paint booth, make sure to wear a mask. Actually, wear a mask (with proper filters, not those cheesy paper masks) anyway, they're $30 at homedepot.
