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.

The sealant worked great on my travel trailer and cleanup was pretty easy. I used it to seal the trim seams, and I was very happy with the results. Only complaint is the nozzle was missing and I had to find one, for the price that was a pain.
