I use this to seal the leak that was coming from the roof rails of the 2007 Honda Odyssey. The original seals have already dried up. Be prepared to have messy hands when using the stuff. This particular sealant will take a few days to cure. People say that they will cure faster when it makes contact with water. There is also a fast cure version that hardens in 24 hours. That one I used for a paddle boat.

Great stuff, holds strong and cleans up great with thinners. Stays soft for 2 days full cure after 7 so if you need it quick use the fast cure, just as good.
