Spot painter - for very precise BC or CC coverage.
I needed to do a very small repair to my BC/CC paint job and wanted to limit the fan size but also wanted the atomization to be about the same as the original shoot. The solution...a shroud. I cut the bottom out of a plastic 35mm film canister and mounted it to the gun tip of my detail gun. Note - the gun tip had to be wound with a few turns of black electrical tape to get the canister to fit snug. It worked well...but you won't want to paint too long with it since the paint will collect in the shroud and eventually drip out the open end. It did the trick for my purposes and the cost was $.00
