I feel soap would actually be counter productive, it would make it easier to slide off quickly if you mess up the order. But seeing as the latex is literally floating on air there isn't much that the soap would do.

I will post a reminder in our team slack to put the video together during our next meeting on Wed.

You cannot pull it on at all. You will need to use compressed air and someone with a reasonably strong arm. Zip-tie/safety-wire one end of the tubing to an air nozzle so that you get a good seal. Next you must plug off your aluminum roller so that air can't flow through it. one person controls air flow, the other holds the tube and tubing and does the hard part. turn on the air and begin pushing the latex on to the aluminum, DO NOT FOR ANY REASON clamp your hand down on the aluminum tube underneath the latex(your hand should never be that far up anyway) or you will get a 100psi balloon animal with a desire to pop. Alternate the airflow on and off to let you move your grip lower on the latex.

If you do not fully understand I can make a youtube video tutorial on Wednesday.
We've found that if you put the air on the end you are trying to pull on to the roller you don't need to plug anything.

Can't tell you which way is faster, it may very well be that yours is...

Thanks! The devil is in the details, and I love to hear them.
