Yes, they wouldn't have been able to sell em if they never sealed :rofl:
Sounds like:
- Bad install on the gaskets (sorry if this offends you, just saying)
- The targa isn't installed correctly. Tighten the back two bolts, the driver's side front, and then the passenger side front. Not doing it in this order will cause it to leak, rattle, and you can strip out the bolts.
- Targa was straightened. It's supposed to be slightley bent so it applies pressure on the middle of the seals. This is obvious when you bolt one front bolt down.
Did you lubricate the seals when first installing the targa after the seals where installed? They tent to bind and get pulled out of where they need to be without some silicone spray.
It may actually be your windshield leaking though...
