Equip the Ps4 pro with liquid metal?

I would like to replace the thermal paste in my ps4 pro with liquid metal from Thermal Grizzly, my question is whether I can simply cover the contacts around the Apu with clear nail polish without any problems?

Is a tried and true tactic. Also from the best overclocker in Germany (DerB8auer). So you can do it without any problems.

Ps: use red nail polish for a few more fps.

Thank you saw the video at the time too😂
