Hey - you bought the Tamiya Enzo? Nice score man. That's a very nice kit. Do yerself a favor, pay close attention to the instructions, and have a look at the Tamiya website - they have quite a number of pictures of the variuos sub-assemblies - very handy if you want to have a look and see what colors things should be. I always try and make my models look as good as theirs (not that it always works......)
Go to the following

The instructions are quite detailed, and really, everything you need is in there - it was for me.
Most things I squirted with the airbrush - bad for you if all you've got is a can of Co2 - hope it lasts the distance. The interior should be sprayed - a little masking is in order - get some low tack masking tape or Bare Metal Foil. I found the red went on better over a primer coat of flat white - better coverage and a more intense red.
Remember, not very many of us build to win contests - we build because we want to - for whatever reason - so if you're Enzo doesn't look like the one on the Tamiya website, ask yerself a question - Did you enjoy building it?
Good luck, Lee Tree
