Basin bottle trap corrosion

[Nea2023]

The Basin bottle trap is in bad condition and begin to loose water due to corrosion (I believe it is lead). May I use pattex putty paste or collak as an emergency solution? How can I loosen the bottle trap nuts? They are so rusty and calcified I am afraid they may break if try to unscrew them. Thank you.

Use what you need to prevent it from leaking as it's only a trap, expect the worst once you attempt the disassembly i.e prepare to have to replace it all so it doesn't matter if you break the nuts. It sounds like they aren't reusable anyway.
