Give some of them a case of beer and they will bead-blast your front porch for you free.
Other places to try are sign-shops, painters, and deck refinishers. They all have sand-blast equipment, and can do a fair aproximation of bead-blast with fine white ashtray sand from Home Depot.
The guns you see with a rough pitted finish were sand-blasted with normal sand containing several grain sizes, or else blasted with course emory grit commonly used to remove rust scale & paint.
True bead-blasting uses tiny glass balls that are perfectly uniform, with no sharp edges. They don't leave pitts.
That hand held blaster will work find,but get glass beads from a good abrasive dealer.The ones that Harbor Freight sells are the lowest quality.I bought a cabinet from HF and it works but you will want to get a dust collector with it.
