Greetings! I've been browsing the net for tips on just this subject and your thread has answered a lot of questions - thank you! I just have one more inquiry - do you know of a way to make the end product of one-part self curing silicones (after curing) softer and stretchier (lets say more like human skin, goal hardness is 10-30 shore A)? The reason I'm asking: I am a resident in heart surgery and I'm trying to make practice models of parts of the human heart and tissue to use for training outside the operating room. As you said the platinum cure silicones are used for this purpose but the price difference is tenfold and they're a bit too expensive for us.

Cattle panels make a good little greenhouse about 8 feet wide. I made one and used it for one year and then went much larger. The metal never rubbed a hole in the plastic. Just bend them with the vertical pieces on the inside. Run your hand over the horizontal pieces and if you find a rough spot, grind it or file it down or wrap it with tape. The ends are the problem, there is a very easy and cheap fix. The wires stick out about 1/2 inch. So I took black pipe insulation as small as you can find and put it on the ends. Then wrap a few pieces of tape every few feet. This covers the ends and protects the plastic. You could use plastic pipe or even garden hose, but you will have to split those. The pipe insulation is foam and is already split. Here is a picture of the building that I built three years ago.

Thanks moonshadow, and bud. . . I went by around noon yesterday, just to run in and pick up some beach towels quickly, and there was alot of activity - the kitchen was completely sealed off with heavy plastic sheeting, floor to ceiling, even taped securely to the floor, with a zipper entry (it was zipped up at the time - and I saw no vendors but heard alot of activity from behind the sheeting). A tube, maybe a foot and a half across, made of the same heavy sheeting, was running from the sealed-off area out through the sliding glass door - venting whatever it was to the outside (most likely through a filter first). I had read online about the need for negative pressure environments in cases of toxic mold and the sheeting was definitely being drawn in toward the area, so that was good. Also they had unloaded the cabinets that were directly beneath the hole in the ceiling and brought the contents into the living room - meaning maybe they took out that whole bank of cabinets to look behind the drywall there as well. I took some pictures and left. Around 4pm I checked back - the vendor's truck was gone and I wanted to be sure everything was locked up (also a bit curious for sure) - this time the vent tube was gone, the whole area was still completely sealed up, and now there were motors running from behind the sheeting (dehumidifier or fans or both). Even the electric cord, which was running through a really small hole in the sheeting, was surrounded by tape, and the small hole was also surrounded by tape. I said all of this to indicate it does seem like they are being super careful. I took more pictures and will go by again this morning (Tuesday) to see what's up. I appreciate your replies and I agree that at this point the complex does seem to be doing everything right. I know they are concerned about long-term damage and making sure everything is ok for the future - it's their investment and who knows where we will be in a year - but they are absolutely taking good care of us with all of this and I really don't think they could've handled it any nicer than they have (so far). I will be really curious to know what they found - do they always test in cases like this or just assume the worst and take all the precautions and that way they are covered for sure? I need to read about air testing or whatever but it seems reasonable to expect that if it was repaired under those negative pressure/sealed conditions and if we (as the residents) didn't uncover the sealed area or stir anything up over the weekend before they started work on Monday (we had moved out on Friday afternoon) - - everything else inside should be ok, right? We did consider asking about another unit - our complex has a program where you can change to another apartment with no penalty - we will see what happens over the next several days. And, we will see how everything shakes out with the whole situation before involving anyone who isn't already involved.

Isn't it a law or something they have to be late? And dress for the part...what's that? For us, living in a small community has its benefits when service people are involved. Poor work usually means they DON'T get business just by word of mouth. On the other hand it may take quite a bit of time before a good service person is available. It took all winter for the furnace to be put in but they did a fine job, we are pleased. If we have an emergency, they are here fairly fast. It's to bad the septic service didn't work out. An hour in your case was a pain in the butt but an hour isn't so bad considering the job they are doing. If you were their first service job though, I would say you had every right to be upset. I still wonder, could the traffic be a problem or cell service? Were they behind in a prior job? I think it would be good if you and this company, if they could negotiate a time better for both of you. You mention going to the doctor. How many of us have sat and waited for them? I know I have.
