Size of Butyl Tape for Winshield/Rear Glass Install, questions on what adhesive to use on glass Options

[porsche914_73]

Hi Guys!

Questions and more questions about windshield/rear glass sealants to use on my rebuild:

1. What is the correct size of butyl tape that I should use when reinstalling the windshield and rear glass?

2. Any reasons why I should use modern windshield sealant instead of butyl tape like the factory did?

3. I'm going for a dechromed look on my rebuild (L96B Alaska Blue with dechrome and roll bar vinyl delete, gloss black painted bumbers, rockers, 2.0 Fuchs). Have anybody had any experience with the windshield rubber moulding kit that 914rubber.com sells?

I believe the butyl tape it should be 10mm as used in a kit on 914rubber.com for the rear glass but want to make sure that is the size. Last time I got a windshield installed, the installer used the black goo adhesive that comes in a tube but excess can be seen on the edge past the chrome moulding so also affecting the height glass and the moulding fitment. Have no doubt that it will hold but maybe he just used too much. What adhesive do you guys use/prefer? There's some butyl tape/rope/cord for sale on eBay (1/4, 3/16 and 5/16 sizes) and it states is suitable for windshields but open to your opinion.
