Ok... I don't know if the piece that go together on the a-piller of the convertibles is the same as on the hardtops, but I was wonder what kind of sealing material is supposed to be used when you put all the pieces back on? It looks like there are three pieces. First the painted "outside trim" piece goes on, then the polished trim piece, then the weatherstripping channel. Looks like maybe some foam weatherstripping goes in between the pieces. Would you use caulking or silicone? Seems like maybe that would squeeze all out. I'm sure several of you have rebuilt this section on your car.    |

Ive never had the A pillar caps off before but I do remember some flattened out caulk on the chrome pieces.

FWIW
On my 67 there was about 2 quarts of a seam sealer type material under the trim. Not sure how much changed between 65 and 67.

The top one in the pic is from a 65 vert it does have a big blob of sealant at the top.   Just for a reference The vert cover is a 1/2 shorter and cut at different angle at the top of the cover. The cover on the right is off the holiday coupe I slid up the vert cover in the pic to show the difference in how there cut. Vert cover measured 20 1/2 inches along the backside where it screws in to the pillar , Holiday measured 21 inches along the backside. The threads of the screws that hold the cover in place also had a sealant on them.  |

it appears that the stainless/aluminum rain gutter has the remnants of a foam strip all down the back where is screws over the mounting points of the outer pillar covers. That just doesn't seem like an idea that would last. I don't have a picture of that at the moment, but if I take one I'll post it.

The black foam in the channel Shane posted is remnants of the roof rail seals.

Its not foam, its the roof rail seal. The seal was glued in and what you have left after 45 years is what was glued on, the rest has rotted and broke away.
Its impossible to install the roof rail strips with a foam tape seal between the strip and the metal. The roof rail weatherstrip is formed to fit into the grooves of the channel.

Are you willing to bet your 442 on it? Mongoose and you are talking about two different things. Yes the weather stripping is preformed and held in place with a liquid sealant. He is asking about the seal between the two scallops that go up A pillar . Look at the photo where I pulled the scallop apart thats a foam tape sealant. the one side is whats left of the weather striping pull the scallops apart there is a foam tape sealant that helps hold the scallops together and create a seal between the pieces.  |

For what its worth both of my cars have a white caulking material as the sealant. The post is a Fremont Cutlass and the Coupe is a Lansing 442. Both are identicle.

Hey, there is no roof rail on a vert! No one is claiming there is but there is seal between the door and the pillar. The A pillar scallops are completely different on a vert then they are on H.C. or post car. The ones from my coupe used a body sealer to seal them together I can post some pics if you would like to see the difference. The vert ones I posted pics of I removed from a 1965 olds cutlass convertible in a junk yard the car still had the plates on it it was last registered in 1972. So i'm sure the foam tape is original. And why would Mongoose be asking about the foam if his vert didn't have it. There are other vert guys on here hopefully they will speak up. |

I definitely can't speak for anything other than my vert, since it's the only '65 I've had, but my pillar components look exactly like the pics Shane posted. The strip of whatever sealing material that was left when we removed the pieces looked very much like what was at one time foam tape. It was consistent in width, and the remaining material has a crunchy, powdery residue, and wouldn't be able to describe it as anything other than a foam tape. So first off, I was surprised that would be there, being that I wouldn't think it would last worth a crap, so I was looking for confirmation. But more importantly, in my case I want to use a "best practice", and put these back together using whatever sealing method others have used (sounds like others with convertibles) to seal this section back up. I can go to the hardware store and get a dense foam tape. We can use silicone (afraid of making a huge mess with squeeze out), we could us some "dum-dum", etc. I know all of you have tried all sorts of things over the years... some things work, some things don't. Thanks for your help guys, and any gals if we have them out there.  |

I know what you mean about that stuff that looks like dried out foam tape,I used a fine line of urethane caulk.You do NOT want silicone anywhere near your car! Lots of people use it or Armor-All of vinyl roofs and on the seats,dash,etc. It is very difficult to get rid of all of it,and it can cause a fish-eye problem when you go to paint! Been there,learned the hard way! (How come this keeps happening) ---bil

Sweet! Appreciate you guys helping out!
What is the "waxy goo" that was under the chrome windshield top cap?
