The manual recommends using weatherstrip lubricant (GM part no 3634770) on the weatherstrip, turns out Amazon carries it

Weatherstrip lubricant

It's a bit spendy, but has all good reviews, apparently a little goes a long way. You can use a cheaper alternative too

Lubricant/weatherstrip

I ordered both and will report back, I'll use the cheap stuff on the less critical weatherstrips and the good on the important/visible ones. Probably a good idea for harsh climates.

Nice! I was just wondering about what product to use on that trim since I'm way too cheap to take it into GM to do.

BMW guys (and any other older German car owners) like Gummifledge
Still new so I can't link it - but search Amazon for nextzett 91480615 'Gummi Pflege Stift' Rubber Care Stick - 3.4 fl. oz

I'm still on my original bottle I bought back in like 2002.

$54 for one ounce?

How about:
"303 Rubber Seal Protectant and Conditioner for Weather Seals - 3.4 fl. oz."
$7 for 3.4 oz.

I'm usually not anal about my cars because ICE autos gets so dirty, and there's so much maintenance already to deal with. But with a BEV there's so little maintenance I can start to care about niceties like weatherstrip conditioning.

Wow, I've never used weather strip lubricant.
Yeah, I bought a brand new 1993 Plymouth Voyager and, to the best of my knowledge, it's never had any weatherstrip lubricant applied (unless the dealer did it back in the days when I had it serviced there). I still have the van, it runs great, and the weatherstripping is still holding up just fine...

I had an 88 Maxima Wagon up until 2016 and the weather stripping looked fine too. Nothing "stuck" or was coming loose to the point I noticed it.

I'm assuming because I'm in a temperate, fairly humid area that the rubber doesn't dry out or experience much frost damage, silicone lubricant is not needed.
