Just like water, it will seek a lower elevation. Given how the iMac logic board is setup on its edge the Liquid Metal TIM will slowly drip down wetting the circuit board damaging it!
I’m sure you would like the system to last as such don’t use any Liquid Metal TIM on your systems that either have a vertical mounted logic board or a laptop which often is stored in a vertical configuration. Horizontal logic boards it makes sense and don’t let it sit in a vertical stand!
As for what to use the GPU it’s self uses the same TIM as your CPU any non conductive or capacitive TIM will do. We all often try to push the limits thinking the testers of things review makes out this TIM is better than the next. While that can be true in some cases, often times today the TIM’s argued about are so close in performance it really makes little difference. Think it this way are you racing your car on the Indi 500? There I can see how a 1/4 of a degree makes a difference.

OK, but what about the VRAM chips? Apple started off using pads and to save time they jumped to a gapping TIM, frankly it’s not as good as the more modern pad materials. For fit I often recommend using some cut up business cards to create a feeler gage to judge the thickness. For most boards .5mm is needed. Just make sure to use a slightly larger piece so the entire VRAM chip is covered.

So while we’ve focused on the physical aspects, you should also install a good thermal monitoring App like [link|https://www.tunabellysoftware.com/tgpro/|TG Pro] so you can keep an eye on your thermals and if need be pump up the fans cooling.
