My brand-X power adapter has lost one of its feet a few times and it no longer has much glue on it. I assume it's rubber and that the other surface is metal. The metal gets hot and I use it for lots of hours at a stretch. Do you have any recommendation for what kind of gluing I need?

Thanks.

I hate the way power bricks get hot, but other than buying an over-spec PSU not much you can do.

Might be worth trying to raise the PSU a little, maybe with larger rubber feet, or even something like shirt buttons!!!

You could try silicone or epoxy glue. Scott.

When silicone glue is used near its expiration date, it works except not so well, and it may not be obvious till later. The adhesion is more temporary. I bought it fresh and used it to glue two feet to the same power brick, so the materials were the same, but I did the two about six months apart. One foot was firmly in place and it was probably the older repair. The other regularly fell off, while still feeling sticky, and probably that one was glued on only about six months before, just before or after the use-by month on the glue tube. Many other kinds of products, particularly when the manufacturers want to protect brand reputation, tend to work fairly consistently over stated lifetimes and at least briefly afterwards, so this is different.

I find that most good glue jobs depend on having clean surfaces. I recommend cleaning with alcohol to remove any oils or grease. I also recommend wearing rubber gloves to prevent transferring oils from the skin to the surfaces, as well as to protect the skin from the glue. Scott.
