Hi,

Just a couple of other tips for painting,  both very simple, but effective. 

I always pre heat my bodies in a spray booth.  Simply a cardboard box with a light inside. About 20 minutes,  then spray.  If you can source a big enough box  you can spray your body inside, saves a lot of messy overspray. 

I only use spray cans, but I do use a Can Gun spray can tool, about £6.00 from Halfords, or online.
I find this makes a huge difference to the way you can use a spray can.  It simply clips onto which ever can you choose to use, and enables you to spray evenly, as the trigger mechanism gives a much more precise action. 
I always spray in a sweeping motion, and go past the body both to the left and right,  as this gives better coverage,  and I stop spraying when clear of the body, never directly over it. 

With the Can Gun spray can tool, or similar,  my results were so much better.....

Practice, will hopefully,  make this all much easier.  Good luck
