Sewn in new rear window leaks: use Coghlan's to seal?

[Dennis Nicholls]

The dealer had sent out my 2000 986 for rear window replacement. The stitching looks good but the window leaks when washing the car. I don't see any sealant applied around the stiches.

Maurice suggests using Cochlan's [sic] Water Based Seam Seal around the stitching (I think it's spelled Coghlan's). https://sites.google.com/site/mikefocke2/havingareplacementplasticwindowsewnin This stuff is available at camping stores and the like.

Do you apply this to the stitching on the outside or the inside? Access to the inside on a Boxster is difficult.

I used the Coughlan's WBSS....it works. There aren't any leaks around the rear window now. But I must caution the reader that it's not an easy application. You can't draw the applicator like a brush, but rather must "daub" each portion of the seam. This makes a ragged and unsightly line. I came back a second time and this time I used masking tape to try to ensure an even line. This was only partially successful.
