T'ing two compressors together will work if BOTH compressors are rated to handle the same P.S.I. compressing capacity and their holding tanks are similiarly rated...that also includes the T'ing components and related materials...the weakest item in all of this plumbing BETTER BE the pop-off values...

And, T'ing everything together will only get you more reserve pressure to last longer, not more pressure overall...two tanks of 200#s of pressure don't add up to 400#s of pressure...it just adds up to just two tanks of 200#s of pressure...period. Your tool will work about twice the time before it quits or the compressors kick back in to re-pressurize...

I use the anti-seize on the bolts and nuts...then the t-bar lug wrench...when the the t-bar quits spinning, I'm done torqueing...I've never had a tire fly off the car, a nut come loose or a nut seize on me while taking a tire off...

Now, the only other thing I could add is this...

Some tire shops have a set of "torque-wrenches" that they use on their air-guns in their shops...each one is marked on the perimeter of the torque-wrench head with a series of black "slashes" that "stop moving" when the proper torque level is reached...(sort of like the "strobe-lines" on the phonograph platters of record players back in the 70s and early 80s).

The "strobe-marks" on the torque-wrenches are aligned with the shop's flourescent lighting so if the mechanic is USING the flourescent lighting, those torque-wrenches are useful in getting you in the ball-park for the proper torque...but if they are using a shoplight (an incadescent bulb) and torqueing your nuts with that...you don't know for sure what the actual torque value is...

Better invest in a manual torque wrench and double-check their work...otherwise, you'll be loosening more than your tire's NUTS...
