What does PU stand for? Lupe 60 Thunderbird Hard Top 64 Imperial Crown Coupe ----- Original Message ----- From: "Rob van der Es" <r.vdes@xxxxxxxxxxxxxxx> To: <mailing-list@xxxxxxxxxxxxxxxx> Sent: Wednesday, March 12, 2008 1:05 AM Subject: Re: IML: Sealing Imperial Roof and Trunk lid Trim Hi Joe, Thanks for your contribution on this subject! I understand the importance of using a proper sealant, since I live in a very wet country called the Weatherlands, ehh the Netherlands I mean :) I noticed that on my 60 Crown a black sealant was used , it has rubberized over the years or maybe it was a rubber sealant that was used. I don't know.. Anyway the connection between the roof trim and the roof is waterproof, otherwise I would have rust stains in my headliner by now. Personally, I don't think that this is the original sealer that the factory has used 48 years ago.. It looks to me if someone has used a sort of window sealant, but it does the job. If I have to remove the roof trim I would use a modern sealant on a PU base, I think silicone is too agressive! There is a kind of acid in it (smells like vinegar) that can cause severe rust problems. It might be aggressive to your paintjob too! Those modern PU base sealants give a very strong bond (as a matter of fact you can use it as glue), are weatherproof and non agressive. And it is clear as glass! Water condense shouldn't be too much of a problem since the paint is still flawless, and if the SS inserts are properly sealed I think everything will be safe. Or at least I hope so :) Robert ----- Original Message ----- From: "Joe Strickland" <jwstrick426@xxxxxxxxxx> To: "Imperial Mail List" <mailing-list@xxxxxxxxxxxxxxxx> Sent: Tuesday, March 11, 2008 5:57 PM Subject: IML: Sealing Imperial Roof and Trunk lid Trim > Along with the discussion of sealing Imperial stainless > steel roof > panels there is the issue of how the roof trim should be > sealed when it > is re-installed.
