Hi,
I am swapping out some capacitors and the replacements are going to need some support as they will dangle from the underside of the PCB. Is it possible to use silicone on he body or anything like that as that would be the easiest method? No room for cable clips or similar based on whats above

sounds like a good idea, presume the glue will last and not affect the PCB tracks it will sit on top of?
Double-sided sticky pads or hot glue are common. Big caps sometimes get cable-tied through holes in the PCB.
There is no room for cable ties as I would have liked that option!
I will go for some sticky pads I think like this Double Sided Sticky Pads Whie, 40 Pcs Adhesive Foam Pads Mounting Pads, Rectangle: Amazon.co.uk: Kitchen & Home
I don't think I need super strength for a couple of small caps 🙂 ?

In the future, when the double faced adhesive needs removal, use solvents, like lighter fluid and acetone, to break the bond. Simple mechanical force may lift copper traces. 😡
ahh - ok, hopefully this will last a good few years 🙂 I could try IPA which I normally have around.
The old caps at 1000 uF and 100 uF in the PS measured 40 nF or so, so I am presuming they are finished, they are from 1983.......

Please do NOT use silicone when attaching components to the copper side! Under the curing process it separates acetic acid which surely will compromise insulation, if not affect the traces themselves.

I've had good results using "nano" tape. It creates an extremely strong hold on smooth surfaces -- metal, pcb, plastic sheathing of caps.

Yes, that's the stuff. It has extremely strong holding power. Warning: although you can remove it, it will lift printed lettering off of plastic. I wouldn't use on caps with a paper exterior unless I never intended to remove and reuse them. But for plastic coated caps I've found it perfect.
Edit: cut it with sharp scissors. It's almost impossible to cut with a knife.

yes, and it is also used in crossovers against vibration. Gives a good bond after degreasing the parts. The difference with the commercials is in the modding 😉
There are "non-corrosive" and/or "electronic grade" silicone sealers that can be used for this purpose. Generic silicone sealer does cure with acetic acid and is corrosive - the acetic acid gives its characteristic smell.
Nothing wrong with hot melt or tape for this, I presume.
