Windshield Sealant Replace Or Reuse Seal

Depends on the year. If its 67 it's 1 yr only as it has Mylar lockstrip and I would only use Precision.
I see people talk about re-use of window seals.

Well, with what I am going through with rear window leaks from a PO, NO F'#+ing way!

I understand a company named Steele is the only ones worth buying though!
