Painting would be the least problems. The magnesium can be time consuming to powder coat. The main problem is "pinholes" that show up during the baking process. The magnesium is very porous, and traps gases under the powder. Then, when you apply heat to cure, "pop" you get pin holes. It takes many coats and color sanding to get it close to perfect, but most don't want to do it. I've had some success with pre-heating the parts for a cycle, then cool down, and then heat again to 200 deg., and apply powder while still hot. This way the powder fills the pinholes a little better, and fewer coats needed...
