If it's your first paint job, I would consider Acrylic Latex.
I am currently painting an Airworld Hawk using this method, acrylics are best when a Matt scheme is done.
Clean up is a breeze with water and it's a household paint so the wife won't complain about smell just overspray!
If you want it glossy you can clear over top with Automotive clear.
Yes Automotive paints are glossy and hard, but land gear up and any paint will scratch, with proper surface prep acrylic is fairly scratch resistant and a lightweight paint job can be done!
Its also much cheaper and you can get just about any colour at the Local H/D.
Just something to consider.
