Any glue that can form a Instant bond in 0F temps?

I'm a bit curious about what you are gluing up to begin with as far as "metal letters"

I couple small C Clamps would work that you could take off easily later for letting a glue set up, epoxy does favor higher temps.

Use a camping portable torch, gas powered.

Up high that may not be effective...

So may need to step things up a bit! Ready the torpedos!

Maybe really strong neodynium magnets could work as a temporary fix if it's something you'll be able to fix better in summer.

I second this. If you use enough and/or big enough N45 neodymium magnets, those will hold up in almost any conditions. The only thing you need to watch out for are sheering forces. Pulling the metal away from the magnets should be virtually impossible but sliding them along one another is a different matter altogether.

I have a block of N45 that's 1x1x2" that I use to hold a steel camera mount through some plate glass and the sheering force is the main issue but that's a big enough chunk that the mount doesn't move in the slightest even with strong winds.

You do need to be careful with the bigger pieces though. You probably won't hurt yourself too badly with a magnet that size but if you go much bigger you can get to the point where you can crush small bones if they happen to get caught between a magnet and a hard place.

Charmonium is on the right track. Buy two of these and metal brace + screw them on to each of the objects you want to Never Move Again (tm). Add a large magnetic panel (think 1'' thick sheet metal plate) across the top of both to keep the object from shearing downward.

Don't get your hand near the contact point, in fact just throw the sign in the cardinal direction of the mounting magnet, it'll probably stick.

Just don't let the magnets fly to the metal, they are fragile. You can use a wood wedge to slowly slide it on.

I can confirm that about 6 HDD magnets will hold a metal door to the frame so strongly you'd think it was bolted to it.

Hmm... I do have lots of dead HDs, I suppose it is time to operate on them.
No idea if the surface is magnetic though, will try when I go back.

What haven't you tried...
