hello all , i was upstate ny today and made a stop by the pilot to get some gas and i took a walk by the blue beacon truck wash . there was about 9 trucks in line to get washed . i was actually impressed with the work they put out.. i know many have names for it like the streakin beacon and so on but i watched 2 trucks get washed from start to finish and they looked pretty darn good.... i was also snoopin on the equipment ...i noticed that they tee off their guns and and use a ball valve to turn on and off chemical induction.. when they were applying chemical (at high pressure) i heard their air pumps kicking on and off .... it didnt look like a dema high pressure down stream injector but i know the chemical was getting fed in the line by a flowjet at some psi ...... they had 3- 4 guns set up on the wall that was just dedicated for 1 chemical ...it looked like they were 2 stepping ... i had to say the place was clean and well run .. i was surprized to see how these employees were working....dont get me wrong im not trying to put them on a high horse but was shocked to see the outcome.. ps anyone have any ideas on what components they use at their guns.. at first i thought they tee'd the line off and put a check valve in place with a ball valve to inject the chemical through at some psi...
