Its a pretty fun job but very dangerous. the gun is putting out 20,000 psi and could cut a limb of like nothing. Ive rarely heard of anyone else doing this work where i live. in these videos they are using bad or improper technique they have the hose behind them and opposite leg forward. you cant blast for very long this way, or it makes it more difficult at least. so does anyone else here do this, or have done it in the past?
