Aren’t needle guns getting banned in some places because the vibration can cause health problem if they’re use over a long period of time?

I think in some cases they’re being replaced with ultra high pressure washers and sand blasting to strip the surface back to bare metal, these methods cause less long term injury but the equipment is much more expensive.

Not where I work. Needle guns, 3 finger scalers and disc sanders are the norm. We used the ultra high pressure washer a couple of trips many years ago but we were the only ship in the company trusted enough to use it. When you are dealing with nearly 40K psi care must be taken. At the same time, and equally important, proper paint prep and application must be followed or you are simply wasting time and paint.

Can’t put into words how much I agree with that Seadog.

If you think needle guns are bad for RSI, try a wire wheel. My experience with angle grinders is such that I really appreciate the smooth, gentle and quiet operation of a needle gun.
