CO in car question

[LetMeOut]

Sorry, ruined this post earlier with accidental edits.

In regards to charcoal method for CO poisoning..

In a newer car (2016-19), it is still necessary to seal up the contours of the doors/windows, like with duct tape? Since newer cars have less air leakage, wondering if it can be done without it
Cuz that sounds like a lot of work

No, it's actually best not to seal it too well.
Some O2 is necessary in order to keep the coals burning, you don't want to create a completely air tight seal.
Just make sure there are no large gaps, especially around lights, etc... and make sure all vents are closed.

When you say "too well", you mean to leave as is, or seal it just not too thoroughly ?
