thanks
hopefully not nailed
as for positive effect, yup it sure will with me walking around and dragging the hose(I like positive flow better than negative pressure) I'm strapping grounding wire on the darn plastic and running it to the ground in the garage. I have had that problem before on the wood/plastic unit and it SUCKED the paint to the body after I turned off the fans. it won't happen again.
the only problem I had today was trying to get a straight line cut in a round 1/2 schedule 40 pipe that I'll use to hold the 4 ft lights in on the sides. I had to put 2 90's on each end and add a second pipe to hold it straight during cutting(then remove 1 section and add another to cut the same) I have 12 more to cut.
