Stupid question

You definately can. Also you can use a gloss varnish instead. Next time try using gloss colors too, however if thinned too much and not properly stirred in tin gloss colors may lose "glossiness".

Tigerman,
Did you spray on the color coat from a can, or an airbrush?
I heat my spray cans in a pan full of WARM water (not hot and definately NOT boiling) - the heat does two things - it lowers the viscosity of the paint, and it charges the particles of the aerosol, making them more active, resulting in an increase in internal pressure inside the can. This, with the thinner paint, will help in reducing orange peel and increasing gloss.
A coat of Future will gloss up any paint job. Just squirt it on full strength - several light dust coats first (this is important) - with about 5-10 minutes drying time in between, then move into a wet coat or two.
Allow to dry for 48 hours and you should have a bullet proof finish.

Thank you Thyamis and Lee. I thought it might work, but I wanted to be sure so I didn't mess it up. By the way Lee, I airbrushed it.

You can use Future or any other good gloss coat. For all my car models, I use Rust-Oleum Gloss coat. After letting it dry (upside down so dust won't settle on the surface, see below) I use Novus Plastic polish. It works wonders on cleaning and shining up a paint job. I also use it to clean canopies on aircraft models and so forth.

PS.....Bend a clothes hanger so you have the hook on one and and the other can be bent to form to the inside of the car body. After spraying each color and gloss coat, hang it upside down to dry! No more dust-hair specs on the fresh color!
