Usually window seals leak between the glass and the rubber, not between the
body and rubber (unless you have a lot of rust there).  I just replaced my
rear window seal for this reason.  It was hard and dried out from being in a
sunny climate for years, but the rubber to body side was fine.  It's over an
inch wide, and there are three or four small fins that seal really well.

Order a seal, pick up a can of silicone spray and some 1/4" cotton rope and
replace it (with an assistant, of course).  You'll thank yourself since you
won't have a bunch of gunk to clean up later!

Up here in Canada you can buy a product by Permatex called Flowable Silicone
Windshield glass Sealant. Comes in a blue blister pack and as the name
suggests, is specifically for leaky seals. I used it on my baywindow about 2
yrs ago, with complete success on the windshield passenger side corner. It
is a very "seeking" product; it crawls down under the seal and you think it
won't flow when you first put it on, but you'd be wrong. I came out a few
hours later and couldn't find where I'd applied it. It had crawled down
under the lip of the seal as intended. I think it's great stuff, and will
probably buy you time. My time has been 2 years; darn, I gotta get on that
body resto. :-) Courtney
