C5 weatherstripping
I bought a 2000 C5 about a year ago, and have gotten a lot of the kinks worked out. Finally decided to tackle the water leaks from the targa top. Replaced with all new weatherstripping from Corvette Rubber. Have adjusted the tip in with the windows. Can't seem to make any progress. Anyone know anyone in the Nashville area that has experience with this? I'm at a total loss...thanks!

There's a pdf floating around that certain members have saved and usually offer to email. It outlines the process of troubleshooting for leaks. Which weatherstriping did you replace?

what works best for me is dielectric grease, on all of the new rubber seals, it helps repell water.

The first thing you should do for water intrusion is to apply dielectric grease to all the seals. Even brand new seals require dielectric grease. It's in the owners manual.If you're still getting water intrusion after that, check to make sure all 4 utters are clean.

utters are fine, I can see where it comes it at, where the front of the targa seals meets the windshield, every now and then the back corner of the side glass, its definitely not bad anymore, but still occasionally happens, thats all i was trying to tell the op, the grease helps a bunch
