Hi Marc, Removal required prying (as evidenced by the scars on the one in the photo). They could be pushed on, but I found a gentle blow delivered with a small ball peen hammer through a short dowel was needed when reattaching them, likely due to paint built up on the knob-like head of the posts. |

Ah... You had "knob-like" posts. My 68 had screws in the corner locations. I will come up with something... Always do.  Thanks everyone!

Why doesn't the Ghia have the rubber seal go all the way around the decklid opening? What exactly is this half seal sealing against? is it just a vibration dampener?

I have always associated the design of the seal to allow for venting of the engine compartment and part of the temperature
control since it will allow air flow. I've never seen anything in writing to verify this. The seal at the bottom prevents metal on metal contact.

When water gets into the upper part of the channel where there is no seal, how does it exit? The remaining path to the back is blocked off by the seal.
Therr are other cars with trunk lids in similar shape that use a full seal. The ghia one can’t really claim to be a seal unless its sole purpose is to not let exhaust gases come back into the engine bay.

You're entirely welcome; you probably already know about the adhesive solvent/remover that won't damage your paint, just in case The anchor caps came with the car, and like most parts I just cleaned them up and reused them. |
Hi Charlie,
When I removed my seals I had a lot of adhesive residue in the channels and it was not coming up very easily. I called 3M and they had nothing to offer. I ended up using carb cleaner which worked but was still a tough job and it damaged the paint which didn't matter in my case (the car was getting stripped anyway).
So what is the name of the adhesive remover that will not damage paint?

I've been using 'Goo-Gone', picked up at the local Homer/Lowes, it has dissolved everything I had to remove, excessive tape residue, adhesive I over used, etc. it's very oily and uses citrus type oils. If I wipe it on a painted part, I clean it off, and have never seen any kind of fade or fog on the paint. If there's something stronger out there, I'd be interested.

| I like NAPA 4070 Universal Adhesive Cleaner (made by Martin Senour Paints). Of the various adhesive removers I've tried it contains the greatest number of organic solvents that I'm familiar with: acetone, n-hexane, naphtha, toluene, methanol, and ethylbenzene. The usual health warnings regarding VOCs apply. The label states "removes adhesives, tar, grease, wax, body sealers and undercoating overspray" and "safe on most cured paints." My paint was unaffected by it, but test it first. FWIW I've been told that gasoline works just as well to remove adhesive, but this NAPA stuff smells good and leaves no residue so it works well to clean an area before you go to glue some weatherstrip down. |

This isn't a trunk lid, it's an engine lid. I don't know of any car that has a full seal on its engine lid.
This is something I've thought about before, and here is my hypothesis. As mentioned, there's no seal on the top half to let additional cool air enter.
But why a half seal on the bottom? A pair of small rubber bump stops would've done fine to prevent metal on metal contact. I think the seal is there to prevent cool air from being sucked out of the engine bay while the car is in motion, as all cars have areas of low pressure directly behind them at speed. With cool air coming in at the top, if there was no seal at the rear, all that cool air would simply pass straight through the engine bay unused.

Thanks for the tip on the NAPA 4070, works like a dream. Some idiot about 15 years ago, looked at the directions several times and still put the seal on the top side! It has been bugging this idiot all that time, and since I am driving her more decided to clean it up

Yes, mostly about the hot exhaust gasses not going back into the engine bay, especially at a standstill
But after buying 2 from 2 different sources (both too stiff, around the corners), it seems that only "vintagecarparts.de" has one pre-formed.
The rubbish ones come up around the corners, and it looks kind of stupid to be honest, the rubber is simply lifting from the paint, even when glued, because it's not flexible enough to go around the corners......

In his Regatta thread, Marc mentions

In looking at my ’70, the decklid seal has also been altered, with removal of the seal’s inner lip across the entire bottom (horizontal) portion of the seal. The attached picture shows the cut made on the pax side, and continues across to the driver side.
I intend to replace with a new seal, but noting it here in case anyone has seen a similar modification.
The seal was last replaced circa 1990, and my memory from that time isn’t clear enough to remember who replaced or the purpose of removing that inner lip. Like Marc, I suspect it was done to facilitate water drainage, rather than rely on the four drainage holes on the deck just forward of the seal.

John, the seal on your car is actually a front trunk lid seal. The reproduction engine lid seals are often very stiff and not a good match so it's not rare to see people use a shortened front seal for the the engine lid.

yes - I suspected that was the case, since it matched my "frunk" seal and I had seen Forum discussion and pictures of that problem with repro engine lid seals.
But in the post, I was just trying to point out the removal of the lip of the seal itself, in case anyone else had come across that. Hadn't occured to me until reading that your seal had been altered, though in a different way.
thanks!
