Radiation shielding on spacecraft?

Question

On spacecraft bound for Mars:

1.  Would super leaded paint on the exterior and interior of a spacecraft provide some degree of radiation shielding?

2.  Would dark skinned persons have an advantage over lighter skinned individuals on long haul space flights?
3.  Could a neodymium boron magnet be installed on spacecraft to repel radiation, would it interfere with navigation?

1.  Yes, "some"
2.  No, gamma rays don't discriminate
3.  A powerful magnet would repel some radiation but I think it would interfere with every other electromagnetic source on the spacecraft that isn't shielded, including but certainly not limited to navigation computers and microwave antennae.  

In the alternative, you could construct a "heavy" spacecraft in space that had, say, a titanium hull.

The earth uses electromagnetic shielding. It seems to me that that would be the logical way of dealing with the problem. Lead paint would be useless. Skin color is irrelevant, neodymium magnets aren't powerful enough, and magnetic energy shouldn't bother inertial or astro nav equipment.

don't know how well it would do under that lead paint
