updating wood frame with glossy black paint

so... for a plan with only 3 steps there is much work to be done.   on the agenda for this weekend:  

• sand.  the wood on fancy chair is covered by a really thick coat of polyurethane or lacquer.  ugh.  it will need to be roughed up a bit so the new finish will really stick.  this is my least favorite part.  it is also the most time consuming as i'm only able to focus on sanding for about 10 minutes at a time (before getting bored, whiny or distracted).  

• spray.  because i've only given myself one weekend to do this (haha), i've decided to use all spray materials.  the positive - spray paint will help ensure thin coats.  the negative - if it rains all weekend i will cry  :(
  

1.  primer = 2 coats

2.  black gloss paint = 2 coats

3.  poly-acrylic top coat = 3 coats
