So he’s saying out loud that he wants to stage a military coup?

ISO8601 is great and all, but even without a common standard, I feel it should either be largest to smallest unit, or smallest to largest. YMD or DMY. Anything else is just asking for misunderstandings.

No clue, but I wouldn’t even be surprised if parts of filtration systems use PFAS themselves as coatings or similar, to reduce friction in pumps, for water proofing etc.

Are those scorch marks an issue beyond aesthetics though? (Genuinely curious, not judging)
