Just add water in Vac-Hanger

I found that if you add water in vacuum hanger, this will help you to avoid damages.

Water is heavier than air, so you will not have blisters on your head. The lymph goes to the head but not much.

I and some PE-ers tested this method and we have good results concerning damages.

PS sorry for my English :)

Is blistering a problem for a lot of guys? I didn’t know water would prevent this.
