Painting a vintage door

In planning the painting of my 3 panel door, I drafted up the following using Publisher.  What color combo is your favorite?  

magnetic paint

For my magnetic chalkboard door or refigerator panel, I orignially planned to buy metal magnetic sheets and paint over those.  After visiting several stores, it was determined I would have to go to a metal store to have them cut the sheets to size.  Instead, I decided to do the harder but maybe cheaper task of using Rustoleum Magnetic Primer - it states that the paint needs to be stirred - they aren't emphasizing this enough.

I should have had Home Depot shake the can for me.  When I opened the can up, it was very liquidy on top but I could feel clumps at the bottom.  It took a lot to stir the quart.  it also was difficult to do this cleanly.  I am still not convinced that I was able to stir it completely.  After mixing it up for almost 10 minutes, I finally decided to try painting.  I poured it into a small tray and started rolling the paint onto my door panels.

The other thing you should know to do before painting with this magnetic primer, wear gloves!  my hands were covered in black primer and it isn't typical paint so it is sticky and harder to get off.  I ended up using a scrubby sponge to get most of the paint off.

How many coats?  If you believe the can, you would only paint 3 light coats.  If you read the blogs and pinterest, you paint the project multiple layers.  I'm going for a really strong magnetic board.  Also, I have several clumps that showed up on my project that I plan on sanding smooth.  With that being said, I plan on painting the panels a minimum of 6 times.  In between coats, I put the paint tray and brush in plastic and put it in the fridge for safe temporary keeping.
