I have read a lot on this site about the preference for for butyl tape over urethane. My installer says he can and will do anything I want but says that the urethane applied with a caulking gun is superior to butyl tape for safety and leak prevention. He said there will be no problem fitting the chrome trim because it lies flatter than the butyl tape.
What is the problem with using urethane? Thank you, Jack |

The problem I have heard (but not experienced) is that the urethane doesn't allow enough flex for the windshield. The car flexes (as 914's do) but the windshield does not and you get cracks or breaks in the glass.
FWIW I've been running urethane for about a year without any problems. |
