Don't worry Derek, I can't finish them all that well either. About all I can do is try to throw on a flashy paint scheme, make it look shiny with some gloss marine varnish, and then photograph from far enough away that you can't tell what it's really like. I know that plenty of guys (particularly those on the US stunt scene) will spend months sanding with wet & dry, apply half a dozen coats of 2-pack clear gloss, etc, and get a stunning finish, but that's way beyond both my skill and patience.
