i did mine almost 10 yrs ago with the tape. i do need to replace my windshield again, due to a vandal, and i was expecting to use the tape again. it acts as a cushion between the metal and glass, and also a spacer, so the glass is not recessed from the chrome. plus it comes with those rubber spacers. i guess if the new windshields come with it already on, it is not needed, but if one doesnt, people dont use it anymore? you just pump caulk on first, and then again afterwards? doesn't seem like much of a cushion.

or Bjorn, your 'sticky stuff' could be the tape i speak of. it is a tar-like ribbon and comes in a roll. it is made by 3m, and is called butyl something or other.
