Tips for permanent isolation?

[Kona64]

Hey guys, i recent got my hands on some hardware i'd like to permanently isolate, and was wondering what experiences y'all have had with different methods so i could chose what would be best.
In this case i'm talking about a gpu since i find them particularly annoying to isolate.
Methods i've looked into are nail polish, varnish, vaseline, and dielectric grease.
I heard varnish may crack depending on the kind used, resulting in the affected part of the board turning white, which is less than ideal for MB's, but isn' so bad for GPU's which don't go as far sub-zero.
Any other experiences?

Thanks guys, i'm using nailpolish for the 980Ti, but will try to get my hands on plastidip and liquid tape for future trials!
