There's nothing that makes your painted model stand ou more than a gloss finish.
Micro Coat Gloss gives you a “'wet look” shine that replicates the new synthetic paint used on the real thing. This is a water clear acrylic resin, which is rough and flexible and adheres strongly to paint and plastic.
The finish should last at least twenty years under ordinary conditions and handling the model, once completely dry, is not an issue.
This should be airbrushed for best results. You can dilute the Micro Coat finishes with distilled water by 10 to 15% for air brushing.
For clean up, before it is completely dry, ordinary warm tap water with a little detergent works great. If you put 3 inches of water in a container beside you while you are spraying you can clean up instantly by removing your paint supply and running water through the airbrush while operating it in the container immersed in water. This is quick and easy and makes no mess. It is especially handy if you are doing a lot of spraying with time in between. It is recommended to use about 25 lbs psi. or more of air pressure to your airbrush. The job comes out smoother and dries faster.
For those who do not air brush, the Preval paint system would also work (see it here). The Preval system is similar tto paint can spraying where the drops are larger, than air brushing so hold the sprayer a little closer to the model and make faster passes. Experiment on an older body first.
