You would have to make a right dugs dinner of the process to get liquid metal on those contacts. Applying the stuff was really easy, I sat and done it with Gamers Nexus guide on you tube. You are putting on a small blob and spreading. Prep the blob on a bit of kitchen roll to get the size you want, then you just put the tip of the syringe on the blob and it sticks to the end, move it over the chip, and ease it off with a cotton bud. It doesn't slide around, needs some work to paste it on and really easy not to go outside the edges. I guess the blob is under half the size of thermal past you would put on for the cooler.
I think you can put nail varnish on those contacts to protect them, but I didn't bother with that.
I also left the black glue on the cpu, remove the IHS glue, supposed to help as a guide to get the lid back on square which I can say it did help. I put a tiny dot of super glue on each corner to stop it sliding. Put it all back together and bobs you aunty, apart from the super glue all up my elbow when I leaned on the kitchen roll, rid raw from scrubbing scotchbrite on it, better than a skin graft!
