The Brain Pot Activation system is the only system that you will need. Removes the guesswork out of setting up your gun. There is ZERO setup. The frustration of atomization. NO atomization with this system. No more overspray. No more cloud of activator (dangerous!). Everything about this system is made for activator. Guess how many "off the shelf" products you can get that are made to withstand the abuse of constant activator exposure. Perfect activation. Dummy proofs activation!
