Yup. Expanding spray foam. That stuff is awesome. Unsure about brand, but looks like Great Stuff Expanding Spray Foam

Nah. You need something to go in the hole and seal it from the inside.

Get some of this stuff - expanding foam - should be able to pick it up at any hardware store. It's basically Styrofoam in a can and has a flexible nozzle - you should be able to squirt it into the holes in the locker, filling it with a foam that will rapidly harden, ruining anything inside and making it very hard to open.

i would recommend getting a can of this or something similar. Drill a tiny hole in the wall, and empty the bottle in the wall near the pipe, it expands and might give you enough insulation in there to keep it from freezing and without opening the wall up. If the wall is white get some of this and just wipe it over the hole you made, or if its in a not so noticeable place, fuck it and leave it or get some similar looking paint and cover it. This is all a last resort attempt before opening the wall and insulating it yourself, no guarantees this will work at all.

If there is significant rot you should look into replacing the compromised sections. To plug holes I have found "GREAT STUFF" works pretty well depending on the size of hole. They sell it at nearly any home improvement store and even Amazon

If the problem is only around the screws, your only real solution would be to replace the bad screws. Again, if you don't feel comfortable getting on the roof because of structural problems it may be time to replace the rotted sections.

You could try some weatherstrip seal?

Or you could try some great stuff foam, it has a "straw", might be able to angle in space?

Oh! It's magic. Spray in whatever weird shape you want, let it expand into a shoggothian mass of foam, then carve into shape. Great for oddly shaped props that really need to be lightweight.

I believe I used Kamui's tutorials for this:

And the particular brand I used was this stuff: http://www.amazon.com/GREAT-STUFF-Filler-Insulating-Sealant/dp/B0002YW0W0/ Had to use two cans for the bow.

Are you able to remedy this situation at all?

Spray Insulation Foam works well.

Are your windows taped up?

Foam strip insulation around your doors and windows?

The foam I used was the first that came to mind when I made it but there's probably an alternative. I wanted something that would fill the center so it was more sturdy and that I could cut and shape. It also had to be light since I'm not all that strong.

The foam that I used isn't really all that bad. Just made sure you wear proper protection (mask, goggles, etc) and have a garage or outdoors to work in.

But if you're a bit concerned still, maybe try this? It's an expanding foam in an aerosol can. But you'd have to make sure you have a tarp out since it sticks to a lot. Once it sets, you can cut at it. I'd make a shield shaped casing and spray the foam into it if I were to use it (kinda like spraying it into a bowl... except shaped like the shield). I honestly don't have much experience with it but I've heard good things about it.

I'm not sure what else would work but I hope this helps! :)

It's more of a joke than it ever was, rap music I mean. Some of the "classic rap" wasn't actually bad, but this new "gangsta rap" crap makes me want to spray Great Stuff in my ears.
