Strive for perfection.

If you do it over, just lightly scuff it with a gray scuff pad, wipe it with wax and grease remover, then a tack rag. Make sure you have plenty of clear in the gun, and spray it right on the ragged edge of running. Holding the gun too far away from the surface, not enough air pressure, high humidity, etc, will all cause it to dry dull. Go on SPI's website, and read "The perfect paint job" if they didn't send you one with your stuff you ordered. Lots of good tips in there. Check out some of Gun Man's videos on You Tube also. I have learned a lot from him also. Good luck. :)
