+1 on waiting 2 weeks. A suggestion would be to do a piece other than the firearm (and for the fun, add a run). Use that piece for "finger touches" to see when it is cured. When you feel it is good enough, try 800 wet/dry sandpaper and work to get the "fun run" out. I would rather screw up a test piece than the firearm.
