 This is Nate Adams with Energy Smart Home Performance, and I want to show you what my foam contractor has started calling Nate Picking. So whatever you do a foam job, this one ran until 11 o'clock last night, got killed himself. So you're going to get some stuff just isn't perfect. And it's my job to come back and just kind of look it over and nitpick and hit various things. So you have little holes like this, these are called pinholes, and they tend to let a lot of heat through them and they can turn in the moisture problems and all kinds of fun stuff. So I hit those, just some various things. And a nice thing about using the orange spray paint like this, I like to see up in here, this is a tough thing to see. The foam guy is wearing a mask with fresh air coming into it, and it's really difficult to see what you're doing really well. So nothing like going back after the fact to catch misses, but with this orange paint all he has to do is spray foam on it until the orange is gone and he knows he's done it. So it's very easy to see through the mask. So if you just spend a little bit of time after the fact and catch all of the little misses that are just going to happen, I mean, nobody's perfect. If you think you're perfect, I will bet you a thousand bucks if you are a foam installer that I can come and find something with a corridor and an infrared camera that isn't perfect on your project. They just are. But with a little bit of extra time, you can catch your misses and get a really nice result for the whole.
