High Pressure Airless Spray Injection Injury Pig Skin Test 

It's what it injects that really messes you up

No problem, stay safe!!

Wow

ChrisKadaver guard act like a small distance from the gun to reach your skin.

Kind of. The pump may be running at a particular pressure, but that can be misleading as the system will not all be at a constant pressure, as diameter of tubes etc. varies, moreso once it's left the paint gun . Pressure is force*area and the nozzle spreads the paint spray out over a wider area the further you get from the nozzle in a kind of cone shape. Closer to nozzle, it's the same force over a smaller area, so higher pressure on skin, so higher risk of injury. Same idea as the military vehicles with thin metal caging mounted with a gap over the main armour plating, so as to prematurely detonate explosives, so that the blast is spread over a wider area of the armour plate

The air gap lets the paint lose kinetic energy. Enough to do less damage.
