Molding Assembly (aka, outer window trim with weatherstrip) Replacement
I really did try to find something on this and am kind of surprised I couldn't. May have something to do with the fact that people refer to these things with different terms, but whatever the case, I'm looking for a cost-effective way of replacing what this parts diagram show as numbers 1, 4, 7, & 10:
Molding Assembly, R Front Door *NH1* (Black) $137.40
72410-SEP-A01ZA
Molding Assembly, L Front Door *NH1* (Black) $137.40
72450-SEP-A01ZA
Molding Assembly, R Rear Door *NH1* (Black) $158.23
72910-SEP-A01ZA
Molding Assembly, L Rear Door *NH1* (Black) $158.23

The windows are operating fine, but the rubber attached to the outer metal trim is falling apart so there are gaps between the window and trim which allow water, small leaves, etc. to fall in there. I'm not interested in spending ~$600 to replace with OEM, but haven't seen any better solutions. The closest post I could find was from @rockstar143 , but I'm honestly not exactly sure what he was fixing in his post.
Shit, a decade later...
I want to say that I ran a little black RTV in that groove...I don't even remember this issue honestly.
Today, I might hit up home depot and look for some kind of weatherstripping that I could retrofit.

Not that it matters, but from your post it looks like you used that adhesive to re-secure the existing rubber weathersripping. My issue is the weatherstripping is non-existent. I went to the car wash today to vacuum out all the small leaves and debris that had accumulated after a hellacious wind storm only for it to suck in most of the remaining weatherstripping. So it's kinda bare and I need to figure out a way to get some other weatherstripping in there...
I've become somewhat friendly with the kid who works at my local Acura dealer's parts dept, so I asked if he could pull one of these "Molding Assemblies" so I could see how they're constructed. Was hoping I might be able to find some sort of generic weather stripping that I could retrofit into the trim, but as you can see in these photos, I don't think it's going to be that simple. It looks like the weather stripping is a single piece of rubber wedged into the length of the trim with those two upward facing fins covered in a moleskin/velour material. Unless someone's done a fix like this before, I may be biting the bullet and paying OEM prices for these stupid parts. Will search the web for used/pulled parts just in case, but the other nuisance is that I don't think this specific part was used on any other Acura models.
Called a few today and visited one, too. They don't want to sell just the molding assembly, preferring to sell the door as a whole. Think I may be screwed here since this outer weather stripping on every single window on my 2007 has pretty much disintegrated. All the other molding looks fine, but this particular part is bad on all 4 windows.
Considering how little my TL's cost to maintain, I'll probably just eat it to get this properly fixed before doing any damage to the inside of the door.
I honestly don't know. I did a search on car-part.com to find junkyards with TL's using a front-door filter since nobody is going to inventory this molding part. I called 3 and visited one. Each place I spoke with said much the same thing: "You're not going to find a place to sell you that part if they can sell the door instead." Makes sense, but still sucks. I'll try to contact a few more tomorrow, but have pretty much resigned myself to having to buy the parts. I have an older 2005 that I'm thinking about keeping as a "spare" car and could swap its parts with the 2007. But if I do that, then it will have the same problem as my 2007, so what will I have actually gained unless I wanted to sell the 2005 with disintegrated window weather seals?
Just removed the front passenger side outer trim with the weather stripping. The Svc Manual says you need to replace this part if you remove it because it will get bent and they weren't kidding. It was not easy pulling it off and I definitely bent the hell out of it. Which is too bad, because now that I have it off, I think I could have used some adhesive and reattached the moleskin/velour trim on the inside of the trim. Instead I need to spend $150 to replace it...
I think that's why I made that other thread in the first place.
In hindsight, that looks exactly like what you did. I'll have to more closely inspect the other three windows to see if that weather stripping is still dangling in there or completely gone. Definitely would prefer a cheap fix than replacing all 4 of those stupid things...
@rockstar143 Some semi encouraging news about this...As mentioned above, I removed the front passenger trim yesterday and pretty much destroyed it in the process. However, now I know how these things are constructed and think I might be able to repair the other three windows and harvest pieces of the one I removed to do so.
Rear passenger side: this one is totally missing the top piece of weather stripping, so I think I can cut a piece from the front one and use it back there.
Rear driver side: this one is missing a 3-4 inch top piece right in the middle. Might be able to slide a piece in or cut a full length new one from the front one.
Front driver side: This one appears to be completely intact, but a portion of it has detached from the trim and is kinda drooping.
So the question is: what's the best thing to use to adhere the moleskin/velour weather stripping back on the rubber/plastic piece that sits inside the trim? Would you still recommend the Permatex black silicone adhesive sealant? Also, since at least one window is going to require a whole new strip, should I try to find a bunch of shims or can you think of something wider I can use to keep it firm while it dries?

Honestly, yes...
when in doubt, rtv is the way.
The fact that it's black is a win but any would work.
They are strong, hold up to flexing and seal stuff out.
I screwed up the door weatherstripping on that same old TL
trying to be my own AAA with a hangar and I was able to recreate
the molding to look decent and not fall apart with it. I've held the rear
caliper covers on the back calipers with clear RTV for years. It works.

@rockstar143 So to be clear, you didn't use the Permatex to adhere the existing weather stripping back to the trim, but instead "molded" the Permatex into a pseudo weather stripping?
As mentioned above, the passenger side rear window had ZERO outer weather stripping left. I took some isopropyl alcohol on a paper towel to clean the surface. I then cut a 23" piece of weather stripping off of the front passenger side that I'd removed. I tried to create a bead of Permatex on the installed trim so I could then affix the piece I wanted to apply, but that didn't go so well: the bead kept falling off into the cavity. Because of this, I applied the Permatex to the weather strip instead. Two notes:
- Wear some sort of rubber gloves when dealing with the Permatex. It's a friggin' mess, so unless you want to spend a ton of time cleaning your hands, just wear gloves
- In hindsight, I probably should have put the Permatex on my gloved finger and spread it around rather than trying to create a perfect bead.
Whatever the case, I finally got it settled. After about 1-2 hours, I decided to raise the window glass so I could get some shims in there. I started with some plastic shims I bought at Ace Hardware and for the side closest to the front of the vehicle, they seemed to do the job. But as I made my way back, the crevice seemed larger so the shims started falling inside the door. Because of this, I decided to use some larger wood shims I got at Lowe's in the rear. That went well, but as I tamped them down, the front plastic shims got looser. I eventually replaced all the plastic shims with the larger wooden ones instead. I used 12 wood shims across the window.
No clue if this is going to work, but I'm going to give it the 24 hours they say it takes the Permatex to cure and then re-evaluate...
I'm describing a different repair.
it'll hold but you might need to cut a strip of something to bridge the two.
black gorilla tape from underneath might also get the job done.

Im on a fit trying to find a way to remove the trim parts 13 and 19 from the first link you reference.
I know its not the side windows like you are having issues with.
NOT SURE WHY rock auto or OEM Honda link shows the DRIP TRIM MOULDING on the same ref. as the side windows... totally diff things.
Which is why I probably couldnt find a link to those full roof length trims on the top of the car on my own, I wouldnt think to call them 'drip', and didnt think to search 'mouldings'. But its in your link so thanks for that.
Mine has one trim #13 that is indented that I want to hopefully not bugger it while unkinking.
But mostly, I have to replace the front windshield glass, and the glass shops where I live are horrific for leaving off parts, sometimes entire glass to roof trimline (I didnt notice it gone on my old Corolla until I got it home, last time I replaced glass) . Or they break clippets but dont tell you or replace them, so when thinks slowly go out of wonk you find out 'hey, those tabs are gone, prob when the glass was swapped'
Acura seems to have a TON of things pinning the glass down whether front, side or back.
I might be fretting but seems like a LOT OF FAIL POINTS for kids who dont have the experience, or werent even born yet when my 04 was made and is long since discontinued off parts and repair lists (I rely on pick and pulls exclusively now, except the rad replacement last xmas)
If anyone off hand has a procedure event recorded in a forum I havent found here yet, would be thankful for the link, I might do everything shy of replacing the glass myself and could use a hint how to get those mouldings off the car w/o damaging
