I never use anything that I can't unmount if needed. Be it a bathroom hook or an enclosure for electronic stuff.
As for heatsinks, I found that polishing the surfaces on 1200 sandpaper and mirror finishing on a piece of cardboard, then applying a very thin layer of thermal grease works best.

FWIW I never use "superglue".
Too hard where you need to just "hold" something, such as securing screws, pot/switch/jack/fuseholder nuts (and as mentioned above it leaves nasty residue behind), too weak (compared to real epoxy) where it needs to hold, as in voice coil joints, large ferrite magnets or gluing sensing transistors or diodes to heatsinks.

Not sure what the actual commercial thermal adhesive contains, but I'll check if a bicomponent resin still has any glueing properties after adding baby face rash powder .At least the conductivity looks ok. https://pubmed.ncbi.nlm.nih.gov/26928396/

I prefer in some cases such as locking nuts from loosening, to use a smear of Loctite or sometimes a tiny dab of plain wood glue works.
Yes.
My go-to glue in those "stands vibration but breaks easy under tool pressure" situations is old style nitro lacquer, cousin of nail enamel.
I buy a can of the automotive use "base paint", which is transparent and does not fill the can , typically 875cc in a 1 liter size, precisely because it expects to be filled with small "pigment paste" pouches in various combinations, which allow a car painter to match any previous colour he´s matching after body repairs.
I buy a can,leave it open on some shelf for a couple days, until it thickens from "paint" to almost "honey" and then load small squirt bottles.
Very useful .
A modern version of what used to be called "speaker cement", way back then the only kind available, and in part responsible of what used to be called "Alnico sound" 🙄

Yeah, I also use nail polish at times.
But these days I feel funny about buying nail polish since I'm a guy.
I shouldn't, but I do.
The cashier might think I'm one of those 'non-binary' types......LOL.
There's a very unnatural trend too of mixing manly things with women's things ...The cashier might think I'm one of those 'non-binary' types......LOL.
In the animal kingdom as well as in african tribes the males have the most yelling posture, colours, the lion has a mane while the boring smaller lioness makes most of the chases for food, the male birds are the more colourful ones as powerful colours actually mean danger in the animal kingdom while females wanted to pass unobserved by other creatures that could potentially attack and kill them.
Then it's about men wearing skirts...well Jesus Christ and his apostles wore dresses, the roman solders who conquered almost the whole of Europe and Braveheart's scots wore skirts...and there's actually a real reason for men to wear skirts instead of pants as the testicles are more productive and the sperm is healthier if exposed to colder weather unlike women ovaries .The nature moved the male's testicles outside the body for a reason! Pants and generally today's fashion is actually a sign of men's slavery to industrialism, his short cut hair is a sign of submission to the military rules to prevent lices, but real men never listen to anyone's rules imposed by force and never like to be part of a conglomerate named army. I remember when I served in the army that the most curageous guys never gave a sh*t on any command and preffered the arrest or various jobs they were given as punishment than taking orders like the rest of us. I finished that time envying them for their attitude.Real men like FREEDOM and defiance at all costs!
We changed women into sexual objects of our imagined desires , then when men get depressed they say they identify with our imposed societal habits on women which now are defined as feminine things...but watch a woman who lived in very harsh conditions and you'll see how manly she devellops when she has no choice of expressing herself as feminine and you'll get that many things that we call feminine or masculine are just linked to imagination and society's habits which are simply different from place to place.
When a man in Africa puts colours like red, pink or yellow on his face he goes to kill lions or to war with other tribes.Woman's beauty expressed by paints are the sign of inaccessibility to her inner circle, she declares war on men trying to seduce her.

Thermal paste is based on aluminum oxide and magnesium oxide powder. It's scale in the kettle 🙂
The powder can be added to the epoxy as a filler.

I had a CD player with overheating DAC chips. These had small depressions as in the picture. I used two spots of epoxy (one in each depression) to bond to the heat sink and surrounded these with silicone heat sink compound. It works well, (or has done for three years) and is so cool that the epoxy is never stressed. One could though I suppose use a non conductive tie of some sort.

I only have aluminium oxide and zinc oxide...but the aluminium oxide is basically cristalized in high grains so I'll try only zinc oxide.
FWIW I make my own thermal paste, out of zinc oxide and red coloured car or water pump type lithium grease.
Which means "my" thermal paste is pink. 😱
I was forced to make it many years ago when in one of our periodical crises none was to be found anywhere so I bought 1 kg of zinc oxide and 1 kg of grease ... easily 10 years ago or more, but the d*mn stuff never runs out!!
IF I needed "thermal Epoxy" for any reason, I could easily mix fine zinc oxide dust with some Epoxy, but never found a reason for it.
Thermal transfer and physical mounting and clamping are very different actions, best handled separately.
