If this link works ok, harbor Freight has one for $50. and replacement
cartridges for $10.

3mm rods

I figure that might be a cheap experiment.

For you Navy deck techs, it's a needle gun.

Wasn't used topside only. I've put plenty of hours with them in the
fireroom. They dimple even heavy steel if not used with a light
touch. The Navy needle guns I used had "needles" about 3/32' to 1/8"'
in diameter, and I saw only that size. I bet if you can get finer
needles you might be able to reduce or eliminate dimpling, at the cost
of chipping speed. As I recall they always worked well on heavy,
brittle paint, which would chip off easily. On soft or thin paint
they were much less effective, but the hammering of the paint would
make it come off easier with a scraper or brush. They *are* about the
easiest to control hand power tool.
