Rick, I have one of those hoods from Hobby Air, it's made of Tyvek. The problem I have with it is that it doesn't turn when I turn my head, so I have to re-adjust it as I use it. I don't remember any strap inside of it, but maybe there is one. That would help.
I thought you were supposed to use a full mask to spray urethane paint because the isos can go into your eyes and cause health problems. Also, when sandblasting how do you keep the sand from trashing the lens? Do the lens convers work pretty well?
I've never seemed to have an issue with the 40' hose. My other section of hose is still coiled up like when I got it. I recall the instructions saying you could set it up for two people.
