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 :)

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.  On '62 models the standard trunk trim piece is a
chrome rib that has several machine threaded studs that are accessed
from the bottom side of the trunk lid.  The same issue would apply to
sealing the roof trim on those years that have the SS roof trim, or even
the conventional models that have roof trim pieces that go across the
top as in '57-59 models etc.  What type of sealer was originally used?
Was it 3-M automotive caulking compound?  Some of the trim I have seen
elsewhere on the '62 I own was a foam plastic pad (usually circular in
shape) that fit between the trim and the paint surface of the body part
with the fastener on it underneath side of the body part.  I have been
thinking about how to re-attach various trim pieces that have holes
through the body sheet metal.  I am leaning toward the possibility of
using clear GE silicone caulk.  It lasts for 20 years or so and remains
flexible.  3-M caulk goes on soft, but eventually dries out.

Paul mentions that some of the stainless steel roof panels had a fiber
pad underneath them (maybe some of them vibrated in the wind and made a
buzzing noise?).  Others had the panels electrically spot welded in
place.  Silicone sealer around the edges might work well and possibly
even contact cement to hold the panels against the roof would work too.
It would require that a person be careful how much contact cement
build-up was added.  It would have to be evenly applied to prevent bumps
or bulges underneath.  Then there is the issue of corrosion.  Any water
that condenses underneath or somehow gets under the edges of the SS
panels would be bound to cause rust.

I don't want to rain on anyone's parade, but those are just some
thoughts that came to mind.
