Great dollops of that white goo between metal to metal thermally conductive surfaces. Heatsink to metal casing in amplifiers etc. I'm not sure why it is even necessary with perhaps 20 square inches of contact and bolts between. I always wipe away with paper etc on first parting but always some gets on my clothing - I've not worn white lab coats for many a year.
Me and white heatsink goo have a very bad working relationship. I only have to walk into the workshop when there's something on the bench using it, and all of a sudden, I'm covered in the rotten stuff, without even going near the bench. At least it seems that way ... :-\
The harware that I always have problems with in the UK , never organised a stock of, is UNF and UNC nuts and bolts for USA kit. And of course,vice versa, repairers in USA never have metric (and lesser extent BA) for UK and Japanese kit
I once got in a lot of trouble with my boss when I was young and worked for a U.S. based company. At that time, I didn't understand that there was a big difference between British 'tongue-in-cheek' humour, and the much more direct U.S. type. I was talking on the phone to one of the designers of a piece of equipment that we sold here in the UK, and asked the guy if he could arrange to send me some screws for the cabinet, as they were a thread that we didn't readily get over here. He asked if I knew exactly what size they were so I replied, quick as a flash, thinking that I was being funny, "I guess that they are round about 3/16ths APF." "What's APF ?" the guy asked. "American Piss Fit", said I ...
Stony silence on the phone. Half an hour later, I was summoned to the boss's office. Apparently, the guy had been really offended by this, thinking that it was a slur on what he considered to be good American engineering, and had called my boss to complain about me. Just goes to show how easily offence can be caused between nations, even when they speak what's basically the same language ... :-)
This is something I'm currently wondering about. I have a fridge-like thermo-electric cooler than has two sections, top and bottom, with different temperatures. The top suddenly stopped getting cool at all, so I took it apart to figure out why. The fans and voltages were all there so I broke down the heat sinks on the bad one to get to the Peltier device. With it isolated, I powered it up briefly and much to my surprise the Peltier device got hot real quickly with the opposite side getting cooler. So the device works, it has to be something with the heat sinks? They did use white goop on both sides, but very little and it was already dried. The heat sinks are milled flat where they make contact with the Peltier device, so my thinking is they need new goop. Looking around I found that Star heat sink compound is about the best you can get, so I ordered some. It just arrived the other day so I'm planning to clean up the old goop, put on some new goop and hope for the best. I don't think too much would be an issue in this case, I want it as cold as possible.
As long as there is no liability involved. If someone else opens it with a 'just torx' tool and is hurt or killed, you could be sued. I just carry the security tools in my toolbox and and ready for a loot of different hardware. I even keep Posidrive in the same toolbox.
You can't fix stupid. You can't even put a band-aid on it, because it's
Here in the colonies, whenever I have a piece of unrepairable Made in Japan, Made in Tiawan, Made in Korea kit, or Made in China POS that is going to the landfill, I use some of my 'mental health' time to disassemble the thing and toss all the screws, nuts, washers, shaft nuts and washers, etc. into a bank of 'metric' jelly jars.

There ya go then ! Anyone from the UK would see it as a quick-fire throw-away line, and would laugh at it. It's sort of intended to be 'barbed', but not in a malicious way. It's a very hard to describe form of humour that is quite prevalent over here.
We have that kind of humor in the US too.. But only amongst friends or people you know fairly well. If a stranger uses sharp humor with me (some do) and It gives the feeling of you dont know me well enough to be poking humor at me, and we also usually take the fact there is ususaly truth in humor.. And honestly you probaly think the US standards are idioic and stupid to still be using when the rest of the world is using the metric system. Thats the feeling I get here in Japan at least. People cant understand why the US uses the old system still.
