How to Use Compound?

Me and my friend just painted his S2k with tamiya color, but no clearcoat, can you guys tell me the right way to use tamiya compound to make the model shiny because it is kind of dull right now.

-Thanks in advance

Is it a metallic color? I recommend clearcoating metallics.

As for "flat" paints, get a soft cotton cloth, apply a little compound to the cloth, and rub the paint gently in circles until you begin to see the paint rub off on your cloth. At that point wipe off the excess compound with clean cloth, and buff it out with clean cloth. Repeat if necessary.

what do u mean by buff it out?

buff - "To polish or shine with a piece of soft material. "
